Hi, I'm trying to route mail to a non-default relay by recepient, i.e. mail should be relayed via default-relay.domain for all recepients except user@domain, which should be routet via nondefault-relay.domain. This works for user@domain and user+ext@domain (c.f. config below), but not for user+other_ext@domain. man 5 transport claims
TABLE SEARCH ORDER With lookups from indexed files such as DB or DBM, or from networked tables such as NIS, LDAP or SQL, patterns are tried in the order as listed below: user+extension@domain transport:nexthop [...] user@domain transport:nexthop [...] As I'm using a normal hash table, I assumed that user+$anything@domain would match user@domain (unless there is a specific entry for user+$anything@domain). Did I miss some option or mis-read the manual? Config: main.cf: queue_directory = /var/spool/postfix command_directory = /usr/sbin myorigin = $mydomain myhostname = test.domain mydomain = domain mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [2001:db8::/64] relay_domains = relayhost = default-relay.domain smtpd_relay_restrictions = permit_mynetworks, reject transport_maps = hash:/etc/postfix/transport /etc/postfix/transport: user@domain smtp:[nondefault-relay.domain]:25 user+ext@domain smtp:[nondefault-relay.domain]:25 Test results: mail to user@domain -> relay via nondefault-relay.domain mail to user+ext@domain -> relay via nondefault-relay.domain mail to user+other_ext@domain -> relay via default-relay.domain Version: 3.5.6 (package from Debian bullseye) Best regards, Jan-Martin -- Dr. Jan-Martin Rämer Systemtechnik Zentrum für Hochschul-IT Rheinland-Pfalz Moselweißer Straße 4, 56073 Koblenz Telefon +49(0)261 9528-906 rae...@zit-rlp.de
