The redirections are # processed by the Postfix local(8) delivery agent. # # Normally, the aliases table is specified as a text file # that serves as input to the postalias(1) command. The # result, an indexed file in dbm or db format, is used for # fast lookup by the mail system. Execute the command # newaliases in order to rebuild the indexed file after # changing the Postfix alias database. # # The input and output file formats are expected to be com- # patible with Sendmail version 8, and are expected to be # suitable for the use as NIS maps. # # Users can control delivery of their own mail by setting up # .forward files in their home directory. Lines in per-user # .forward files have the same syntax as the right-hand side # of aliases entries. # # The format of the alias database input file is as follows: # # o An alias definition has the form # # name: value1, value2, ... # # o Empty lines and whitespace-only lines are ignored, # as are lines whose first non-whitespace character # is a `#'. # # o A logical line starts with non-whitespace text. A # line that starts with whitespace continues a logi- # cal line. # # The name is a local address (no domain part). Use double # quotes when the name contains any special characters such # as whitespace, `#', `:', or `@'. The name is folded to # lowercase, in order to make database lookups case insensi- # tive. # # In addition, when an alias exists for owner-name, delivery # diagnostics are directed to that address, instead of to # the originator. This is typically used to direct delivery # errors to the owner of a mailing list, who is in a better # position to deal with mailing list delivery problems than # the originator of the undelivered mail. # # The value contains one or more of the following: # # address # Mail is forwarded to address, which is compatible # with the RFC 822 standard. # # /file/name # Mail is appended to /file/name. See local(8) for # details of delivery to file. Delivery is not lim- # ited to regular files. For example, to dispose of # unwanted mail, deflect it to /dev/null. # # |command # Mail is piped into command. Commands that contain # special characters, such as whitespace, should be # enclosed between double quotes. See local(8) for # details of delivery to command. # # When the command fails, a limited amount of command # output is mailed back to the sender. The file # /usr/include/sysexits.h defines the expected exit # status codes. For example, use |"exit 67" to simu- # late a "user unknown" error, and |"exit 0" to # implement an expensive black hole. # # :include:/file/name # Mail is sent to the destinations listed in the # named file. Lines in :include: files have the same # syntax as the right-hand side of alias entries. # # A destination can be any destination that is # described in this manual page. However, delivery to # "|command" and /file/name is disallowed by default. # To enable, edit the allow_mail_to_commands and # allow_mail_to_files configuration parameters. # # ADDRESS EXTENSION # When alias database search fails, and the recipient local- # part contains the optional recipient delimiter (e.g., # user+foo), the search is repeated for the unextended # address (e.g., user). # # CONFIGURATION PARAMETERS # The following main.cf parameters are especially relevant # to this topic. See the Postfix main.cf file for syntax # details and for default values. Use the postfix reload # command after a configuration change. # # alias_maps # List of alias databases. # # allow_mail_to_commands # Restrict the usage of mail delivery to external # command. # # allow_mail_to_files # Restrict the usage of mail delivery to external # file. # # expand_owner_alias # When delivering to an alias that has an owner- com- # panion alias, set the envelope sender address to # the right-hand side of the owner alias, instead # using of the left-hand side address. # # owner_request_special # Give special treatment to owner-xxx and xxx-request # addresses. # # recipient_delimiter # Delimiter that separates recipients from address # extensions. # # BUGS # Regular expression alias lookup tables are allowed, but # substitution of $1 etc. is forbidden because that would # open a security loophole. # # STANDARDS # RFC 822 (ARPA Internet Text Messages) # # SEE ALSO # local(8) local delivery agent # newaliases(1) alias database management # regexp_table(5) POSIX regular expression table format # pcre_table(5) Perl Compatible Regular Expression table format # # LICENSE # The Secure Mailer license must be distributed with this # software. # # AUTHOR(S) # Wietse Venema # IBM T.J.
