Hi list,
I have a small problem with recipient_delimiters contained in usernames. Recently I have extended recipient_delimiter from "+" to "+-" in both Postfix and Dovecot (using lmtp) and now any user that have a '-' in it's username can't receive mail anymore, because lmtp truncates the localpart after the '-' and of course can't find the first half in the user database.
To illustrate: given an account "foo-bar@example.com", I get the following log entry from postfix: Mar 9 09:31:43 batleth postfix/lmtp[6196]: 9A7BA33E005B: to=foo-bar@example.com, relay=batleth.sapienti-sat.org[private/dovecot-lmtp], delay=20, delays=20/0.01/0.01/0.08, dsn=5.1.1, status=bounced (host batleth.sapienti-sat.org[private/dovecot-lmtp] said: 550 5.1.1 foo-bar@example.com User doesn't exist: foo@example.com (in reply to RCPT TO command))
Is there any way to tell lmtp to first look for <user><delimiter><extension> and if that fails look for <user> only (the reverse order would be ok, too)?
Thanks in advance, Juri
