Any table that supports keys of the form: - localpart@domain - @domain (catchall) - locapart (flat-address-space local domains) also supports "user" lookups sans address extension: - user@domain - user (flat-address-space local domains) So support for the recipient delimiter is "pervasive". This should probably be mentioned somewhere in the README, and perhaps a few additional manpages, like virtual(8) (virtual_{mailbox,uid,gid}_maps), or smtp(8) (generic(5) lookups), ... Presently mentioned in: $ git grep -lE 'address extension|recipient_delimiter' proto man man/man1/postdrop.1 man/man1/smtp-source.1 man/man5/aliases.5 man/man5/canonical.5 man/man5/generic.5 man/man5/lmdb_table.5 man/man5/postconf.5 man/man5/socketmap_table.5 man/man5/tcp_table.5 man/man5/virtual.5 man/man8/cleanup.8 man/man8/local.8 man/man8/pipe.8 man/man8/smtpd.8 man/man8/trivial-rewrite.8 man/man8/virtual.8 proto/ADDRESS_REWRITING_README.html proto/MULTI_INSTANCE_README.html proto/STANDARD_CONFIGURATION_README.html proto/VERP_README.html proto/aliases proto/canonical proto/generic proto/lmdb_table proto/postconf.proto proto/socketmap_table proto/tcp_table proto/virtual The docs for the various "_maps" parameters in postconf(5) should mention the recipient delimiter (or address extension) when applicable. The main thing worth specific commentary is that $propagate_unmatched_extension controls when/whether the extension is added back to table lookups results. The recipient delimiter is global, there is presently no support for a different recipient delimiter for different domains. -- Viktor. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
