Further arguments (up to 5) can be used to # # specify specific return values from lookups. Temporary lookup failures are # # ignored unless a third argument is given, which must be either `t' or a full # # error message. By default, any successful lookup will generate an error. # # Otherwise the result of the lookup is compared with the supplied argument(s), # # and only if a match occurs an error is generated. # # # # # # STARTTLS: # # # # Transport Layer Security (TLS), provides authentication (identification). # # Starttls of the communication partner), privacy/confidentiality # # (communication is not intercepted Starttls or eavesdropped), and integrity # # (message has not been modified). TLS uses different Starttls algorithms for # # encryption, signing, message authentication etc. # # # # The variables used in the TLS configuration are: # # # # o UseTLS : Enable the TLS handshake in the SMTP transaction. (True/False) # # o CERT_DIR : The directory for storing sendmail certificates. # # o confCACERT_PATH : The path that stores the certificates of all the # # Certificate Authorities a sendmail server knows about. # # o confCACERT : The file containing the certificate of the Certificate # # Authority that issued this sendmail server's certificate. # # o confSERVER_CERT and confCLIENT_CERT : Typically refer to the same # # certificate, the server's certificate used when acting as a # # server and when acting as a client. # # o confSERVER_KEY and confCLIENT_KEY :The private keys that correspond to the # # sendmail server's certificates. # # # # Milter: # # # # Milter provides third-party programs to access mail messages as they are # # being processed by the Mail Transfer Agent (MTA), allowing them to examine and # # modify message content and meta-information. Filtering policies implemented by # # M ilter-conformant filters may then be centrally configured and composed in an # # end-user's MTA configuration file. Possible uses for filters include spam # # rejection, virus filtering, and content control. # # # # Queue Groups: # # # # In addition to the queue directory (which is the default queue group called # # "mqueue"), sendamil can deal with multiple queue groups, which are collections # # of queue directories with the same behaviour. Queue groups can be defined # # using the command: # # # # QUEUE_GROUP(`name', `equates') # # # ################################################################################## ################################################################################## ################################################################################ # Localizable Classes and Macros: # ################################################################################ # # # Aliases for Local Host (class w): # # # # This configuration will automatically recognize that mail to users # # at the local host or any of its host name aliases or CNAMEs should # # be delivered locally. Other host names that you wish to recognize # # as local can be added to class w as either a simple class # # definition (Cw) or a file class (Fw). Any names added to class w # # must be canonical names. # # # # For example, by default, only the server of an HP-UX nfs cluster # # runs the sendmail daemon, and mail from the clients is sent out # # with headers indicating that it originated on the server. # # # # However, you might want the server also to accept mail addressed # # to users at the clients. You could have nameserver MX records # # directing mail for the clients to the server, and make the server # # recognize the clients' host names as local. # # # # By default class W is defined in 2 stages. Using Cw to add the name # # "localhost" to class w and then adding the names listed in the file # # "/etc/mail/sendmail.cw" to class w using Fw. To add other hostnames # # to class w just add the names as new lines in the file sendmail.cw. # # # # # # My official domain name or Fully Qualified Domain Name - FQDN (Dj): # # # # This is required only if sendmail cannot automatically determine your # # domain. If you are not using DNS, and the official host name (ie, # # the first entry in /etc/hosts following your IP address) is not a # # fully-qualified host name, then sendmail will have difficulty resolving # # your domain name. You MUST modify the $j macro by replacing .Foo.COM # # with your actual domain name. If you do not, you will see a warning # # message in your syslog, that might even get echo'd to your console # # when sendmail starts up. # # # # For example, if you see this warning: # # # # WARNING: local host name (sys1) is not qualified; fix $j in config file # # # # then you need to uncomment the Dj macro and add your domain. # # # # Change the line: # # #Dj$w.Foo.COM # # to # # Dj$w.hp.com # # # # where hp.com would be the name of your domain. Then that warning # # message will go away. # # # # # # Masquerade as (DM): # # # # If you wish to have mail appear to be from some host or location # # other than the local host, set macro M to the name you wish to # # masquerade as. This is also know as site hiding and was set using # # the DY macro in previous releases of hp-ux. This might be used to # # make mail appear as from a site rather than an individual host or # # from a central mail hub. Note, however, that just making mail # # appear to be from a different location does not mean that the # # receipient will be able to reply to the email. If you use this feature # # you will also need to be sure that you can reply to the email. # # # # Genericstable : # # # # This feature will cause unqualified addresses (i.e., without a domain) # # and addresses with a domain listed in class {G} to be looked up in a # # map and turned into another ("generic") form, which can change both # # the domain name and the user name. The default map definition is: # # # # Kgenerics dbm /etc/mail/genericstable # # # # The key for this table is either the full address, the domain # # (with a leading @; the localpart is passed as first argument) # # or the unqualified username (tried in the order mentioned); # # the value is the new user address. If the new user address # # does not include a domain, it will be qualified in the standard# # manner, i.e., using $j or the masquerade name. Note that the # # address being looked up must be fully qualified. # # # # Notice: if you use MSP, the MTA will only receive qualified addresses # # from the MSP. Hence you need to add your domain to class {G}. # # The same types of addresses as for masquerading are looked up, # # i.e., only header sender addresses unless the allmasquerade # # and/or masquerade_envelope features are given. Qualified # # addresses must have the domain part in class {G}; entries can # # be added to this class as follows # # # # C{G}abc.com cde.com # # #F{G}/etc/mail/genericdomains # # # # Alternatively, to read the list of domains from a file # # (/etc/mail/genericdomains), comment the above C{G} line and # # edit the F{G} line as follows # # # # #C{G}abc.com cde.com # # F{G}/etc/mail/genericdomains # # # # Non-local domains that should also be masqueraded (class M): # # # # If the macro M is set using DM then addresses listed with the local # # hostname ($w) will be masqueraded or hidden. If you have other # # domains that you also wish to "hide" or masquerade put them in # # class M as: # # # # CM other.hidden.location # # # # # # User names which will not use masquerading (class E): # # # # If we are doing masquerading (aka site hiding) we may still wish to # # have mail from some users appear with our real hostname instead of # # the masqueraded name/location. In order to do this, add the names # # to class E as: # # # # CE root # # # # # # Known direct UUCP connections (class U) # # # # This class contains the names of all the hosts to which we are # # directly connected via UUCP. # # # # # # UUCP relay for unresolved ! addresses via UUCP (DX): # # # # If your host has a UUCP path to another host with wider UUCP # # connectivity than your host has, it may be appropriate to route # # UUCP mail to hosts to which your host cannot connect through # # this other host, which will attempt to relay messages to their # # final destination. Courtesy suggests that you get permission from # # the administrator of that host before relaying mail through it. # # To implement UUCP relaying via UUCP, first define the macro X, on # # the line beginning DX, as either the relay host name or the path # # to the relay host. # # # # After defining the UUCP relay, uncomment the three lines in # # Ruleset 0 following the comment: # # # # # pass unresolved UUCP addresses to the UUCP relay (via UUCP) # # # # # # UUCP relay for unresolved ! addresses via SMTP (DW): # # # # If you can mail via SMTP to the host you wish to use as a UUCP # # relay, define the macro W, on the line beginning DW, as the name # # of the UUCP relay host. # # # # Note that in this case, the macro W must be a single host name, # # not a path. Note also that the name of any host defined as a # # relay to be reached via SMTP must be an official host name; in a # # domain naming environment this must be a fully qualified domain # # name. The canonicalization operator $[ $] is not applied to relay # # names. # # # # For example, if domain names are not in use at your site, and # # if the relay host's official name is pzzz, define W: # # # # DWpzzz # # # # Then uncomment the line in Ruleset 0 following the comment: # # # # # pass unresolved UUCP addresses to the UUCP relay (via SMTP) # # # ################################################################################ # Localizable Options: # ################################################################################ # # # Automatically rebuild the alias database (option AutoRebuildAliases): # # # # This option causes sendmail to attempt to rebuild the alias database # # when needed. Setting this option may cause excessive overhead and is # # not recommended. To enable this option uncomment the following line and # # equate it to True: # # # # #O AutoRebuildAliases=False # # # # NOTE: This option is deprecated and will be removed from a future # # version. # # # # Delivery Mode (option DeliveryMode): # # # # The default delivery mode is "background": the user agent # # invoking sendmail will return immediately, and sendmail will route # # the mail in the background. Other options are "interactive": # # sendmail will not return control to the program invoking it until # # the mail has been routed; and "queue": sendmail will put the # # message in the mail queue and a sendmail queue process will route # # the message later. Delivery mode is defined on the line beginning # # with: # # # # O DeliveryMode=background # # # # # # Error message header/file (option ErrorHeader): # # # # This option may be set to the name of a file that contains extra # # information to be sent back with any errors messages generated by # # the local sendmail. This might, for instance, be a message with # # information about current problems or who to contact for sendmail # # problems. To use this option, create your error mesage and then # # modify the line starting: # # # # O ErrorHeader=/etc/mail/error-header # # # # to point to the file which contains your error message. # # # # # # Queue mail for expensive mailers (option HoldExpensive): # # # # This option may be used to force sendmail to queue message that will # # be sent via a mailer that has been marked as expensive (using the # # "F=e" mailer flag). To put this option into effect set the option: # # # # O HoldExpensive=True # # # # # # Logging Level (option LogLevel): # # # # Logging level determines the classes of events which will be # # logged by sendmail in /var/adm/syslog/mail.log. By default the # # log level is 9, which reports successful deliveries (and the # # mailer and host used for delivery), queue daemon startup, alias # # database rebuilds, and various errors. More detailed information # # is reported with higher log levels. In particular, log level 11 # # reports the MX host (if any) and internet address to which mail # # was delivered. Refer to the documentation for details. # # # # Note that log level also affects the information reported by # # sendmail -bv. At log level 10 and higher, sendmail also reports # # the mailer and host that would be used for addresses that are # # "deliverable." # # # # This option is defined on the line beginning: # # # # O LogLevel= # # # # # # Maximum message size (option MaxMessageSize): # # # # This option restricts the maximum message (in bytes) that sendmail will # # accept from a remote system. If a message larger that this limit is # # originated form the local system, the message will be truncated to the # # limit. # # # # To enable this feature uncomment the line: # # # # O MaxMessageSize=100000 # # # # # # Postmaster Copy (option PostmasterCopy): # # # # If this option is set to a valid address, when an undeliverable # # message is mailed back, a copy of the message header (but not the # # message body) is delivered to the PostmasterCopy address. It is # # suggested that this address be "Postmaster" since RFC 822 requires # # that there be a valid Postmaster address on all mail systems, and # # since sendmail also attempts to deliver undeliverable error return # # messages to Postmaster. # # # # Postmaster should be aliased locally to the (local or remote) # # address of the person responsible for mail system administration. # # # # To enable this feature, uncomment the line: # # # # #O PostmasterCopy=Postmaster # # # # If desired, replace "Postmaster" with the appropriate address. # # # # Timeouts (option Timeout.*): # # # # Sendmail has a number of adjustable timeouts. Under normal conditions, # # the default timoeuts will work without adjustment. You may, however # # wish to adjust the timeouts associated with temporarily undeliverable # # mail. If it is determined that the delivery failure is permanent, then # # sendmail will return the mail to the sender at at once. If the failure # # is deemed to be a transient or temporary problem, sendmail will queue # # the message and keep trying. # # # # The option: # # # # O Timeout.queuewarn=4h # # # # controls how long the local sendmail will hold a message before a # # warning message is sent to the sender (in this example 4 hours). # # Only one warning message will be sent. If the option is not set or # # set to a value of zero, no warning will be sent # # # # The option: # # # # O Timeout.queuereturn=5d # # # # controls how long a message will be held while attempting delivery # # before the local sendmail gives up and returns the message to the # # sender (in this example 5 days). The default value is 5 days. # # # # # # Try hosts with no MX records (option TryNullMXList): # # # # Sendmail always tries to lookup MX records for the destination host # # and deliver to the Mail Exchanger with the best precedence (lowest # # number). If there are no MX records listed for the host or we are # # the best Mail Exchanger in the list (lowest number), then we have a # # "null MX list". In such a case, sendmail will report a configuration # # error unless the option "TryNullMXList" is set. If this option is set # # then sendmail will try to deliver directly to the destination host. # # To disable this feature and have sendmail just return the mail with an # # error, comment out the line: # # # # O TryNullMXList # # # # # # Queue-Only Load Average (option QueueLA): # # # # In order to limit load on a very busy system, sendmail can be # # configured to queue up low priority messages rather than attempt # # delivery immediately if the five-minute load average is greater # # than some integer value, by default 8. This value is defined on # # the line beginning O QueueLA=. # # # # Refuse-Connections Load Average (option RefuseLA): # # # # In order to limit load on a very busy system, the sendmail daemon # # can be configured not to accept SMTP connections if the five- # # minute load average is greater than some integer value, by # # default 12. This value is defined on the line beginning # # O RefuseLA=. # # # # # ################################################################################ # Routing Options: # ################################################################################ # # # The supported routing options are described below. Options for # # routing local mail, SMTP mail, UUCP mail, OpenMail mail and X.400 mail # # are described. # # # # To implement any of these options, edit a copy of this file # # according to the instructions for that option. With minor # # exceptions, noted where appropriate, the options are independent # # of each other; you can implement any of them or none of them. # # # # Some of these options require that you have installed and # # configured other software not part of the core networking products # # # # # # Operator precedence: # # # # It is generally agreed that mixed addresses, being ambiguous, are # # abhorrent. This configuration file interprets address operators # # in the order '@', '!', '%'. # # # # Changes to this precedence are not supported! # # # # Mixed addresses are resolved as follows: # # # # Address Mailer Host User Destination # # ------- ------ ---- ---- ----------- # # user%hostA@hostB tcp hostB user%hostA@hostB user@hostA # # hostA!user@hostB tcp hostB hostA!user@hostB hostA!user # # hostA!user%hostB uucp hostA user@hostB user@hostB # # # ################################################################################ # Routing of local mail # ################################################################################ # # # By default, all mail with just a user name or a user name at a host # # that we consider to be local (also see Class W above) is delivered locally # # using the local mailer. In some cases this may not be desired. If sendmail # # is running on a discless client, for instance, then we would prefer to # # pass the mail over to the discless server for local delivery. Or we may # # just wish to have all mail send to a central mail hub. # # # # Send all local mail to the "mail hub" (DH macro): # # # # By setting the macro H (line starting with DH) to the name of the mail # # hub, all mail that is destined for a local user will, instead, be forwarded # # to the same user on the mail hub. # # # # Names that should be delivered locally, even if DH and DR are set (Class L): # # # # If you are sending local mail to a hub there may still be some users # # whose mail should be delivered locally such as root. Class L lists # # such users. To add a user to this class, define them as part of class # # L as in: # # # # CL root bob mary # # # # # ################################################################################ # Routing of non-local mail: # ################################################################################ # # # # # By default, sendmail will attempt to send all email with an address of # # the form user@host via the SMTP protocol over TCP/IP. If the # # nameserver is in use, an MX record may direct sendmail to route # # mail for that host to some other host acting as a "mail exchanger" # # for the host in the recipient address. If there is no MX record # # for the target host name then gethostbyname(3n) must be able to return # # a valid internet address for the host AND the option TryNullMXList must # # be enabled or else the delivery will fail. # # # # # # Relay all non-local mail to the "Smart" relay host (DS) via smtp: # # # # This macro is optional. If you wish to send all non-local mail # # to a smart relay via SMTP just set macro S (DS) to the name of the # # smart relay. If this macro is not set, then all mail addresses to # # a non-local user will be send to the relay. # # # # # # Relay all non-local mail to the "Smart" relay host (DS) via UUCP: # # # # In some cases, the smart realy defined above may actually be connected # # to your host via a uucp link. If this is the case, and you wish to # # route all non-local mail to the smart relay via uucp you will need to # # make two chnages to this file. First, set macro S (DS) to the name # # of the smart relay, in this case the name should appear in the the list # # of names returned by the uuname(1) command. Second, you will need to # # uncomment the line in ruleset 0 following the comment: # # # # # Pass mail to smarthost via uucp # # # # Direct SMTP connection with local domain: # # # # To deliver mail destined for hosts within the local domain directly, # # while sending all other mail to the "Smart Relay" listed above, you # # will need to uncomment the line in ruleset 0 following the comment: # # # # # See if we are supposed to deliver to hosts in the local domain # # # # Also ensure the $m macro gets defined. It gets defined internally # # from $j macro. You can check if it is set by doing the following: # # # # sendmail -bt # # > $m # # # # If $m is undefined, you can define it as follows: # # eg: if FOO.com is your local domain, define it as # # DmFOO.com # # # ################################################################################ ################################################################################ # Routing of UUCP mail: # ################################################################################ ################################################################################ # Routing of X.400 mail: # ################################################################################ # # # By default, mail to X.400 style addresses will be rejected as an # # error.

OpenMail Relay (OpenMail delivery agent on a remote host): # # # # If the OpenMail delivery agent runs on a different host, for # # example, "tortue.ordinary.com", sendmail on tortue must be # # configured to route OpenMail mail to the OpenMail delivery agent. # # # ################################################################################ # # # Sendmail with LDAP # # # # Sendmail supports the use of the LDAP protocol for address lookup. # # The default LDAP map specification is as follows: # # # # O LDAPDefaultSpec=-h localhost # # This needs to be set before any LDAP maps are defined. `localhost' must be # # replaced by the LDAP server name. # # # # Lookups via LDAP are entirely defined by the switches specified. # # # # The different switches that are widely used by most applications are : # # # # -b ldap search base # # "Directory" in the ldap "tree" where searching begins. # # # # -d bindDN # # The BindDN parameter is used to specify the DN value for the # # LDAP bind request. # # eg: -d"cn=ldap://:389,dc=edatl04,dc=atl,dc=hp,dc=com" # # # # -h ldap servers # # Space separated string of servers that support ldap at your site. # # eg: -h "ldap1.hp.com ldap2.hp.com" # # # # -p port number # # Port number where LDAP service is available. # # eg: -p 33333 # # # # -k ldap search string (key) # # String that defines how the ldap map takes it's input value and # # constructs an ldap search. # # eg: -k (&(objectClass=mailrecipient) (mail=%0)) # # # # -v ldap attribute # # The value that replaces the origin string in the map. # # In most cases this will be the rfc822 email address. # # eg: -v mailroutingaddress # # # # Note: Any "ldap-style" options must be double-quoted and must follow # # immediately after the option (i.e. no spaces between the option and # # the quote) # # # # To enable LDAP, you have to generate sendmail.cf file with `ldap_routing' # # feature using the gen_cf utility. # # # # When this feature is enabled, two new ldap maps (ldapmh & ldapmra) # # will be defined in the configuration file. # # These maps defines a schema that provides a means by which # # a directory entry that represents a mail recipient can provide # # information enabling MTAs to route messages to the recipient's # # "home" MTA. # # # # # ################################################################################ # # ############################################################ # Original file built with the following M4 files # ############################################################ ##### $Id: cfhead.m4,v 8.116 2004/01/28 22:02:22 ca Exp $ ##### ##### $Id: cf.m4,v 8.32 1999/02/07 07:26:14 gshapiro Exp $ ##### ##### $Id: generic-hpux10.mc,v 8.13 2001/05/29 17:29:52 ca Exp $ ##### ##### $Id: hpux11.m4,v 8.1 1999/11/19 05:22:59 gshapiro Exp $ ##### ##### $Id: generic.m4,v 8.15 1999/04/04 00:51:09 ca Exp $ ##### ##### $Id: redirect.m4,v 8.15 1999/08/06 01:47:36 gshapiro Exp $ ##### ##### $Id: use_cw_file.m4,v 8.11 2001/08/26 20:58:57 gshapiro Exp $ ##### ##### $Id: always_add_domain.m4,v 8.11 2000/09/12 22:00:53 ca Exp $ ##### ##### $Id: proto.m4,v 8.710 2004/07/27 17:32:48 ca Exp $ ##### # level 10 config file format V10/Berkeley # override file safeties - setting this option compromises system security, # addressing the actual file configuration problem is preferred # need to set this before any file actions are encountered in the cf file #O DontBlameSendmail=safe # default LDAP map specification # need to set this now before any LDAP maps are defined #O LDAPDefaultSpec=-h localhost ################## # local info # ################## # my LDAP cluster # need to set this before any LDAP lookups are done (including classes) #D{sendmailMTACluster}$m Cwlocalhost # file containing names of hosts for which we receive email Fw/etc/mail/sendmail.cw # class S defines hosts to which you connect directly for SMTP mail #FS/etc/hosts.smtp # my official domain name # ... define this only if sendmail cannot automatically determine your domain #Dj$w.Foo.COM # host/domain names ending with a token in class P are canonical CP. # "Smart" relay host (may be null) DS # LUSER-RELAY # place to which unknown users should be forwarded # # The site to which mails to unknown users should be forwarded. # To use this feature please uncomment the rules in the fourth # section of Ruleset 5. #Kuser user -m -a<> #DLname_of_luser_relay # operators that cannot be in local usernames (i.e., network indicators) CO @ % !
