Hidy-ho,

I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *@example.com (everything) to go to virtual@example.com, where virtual is a valid virtual user. It seems that things are getting as far as LMTP, but then the mail gets bounced. To wit:

Aug 21 08:02:50 hostname postfix/lmtp[4914]: 8DF8E9AFE6: to=test@example.com, relay=mail.example.com[private/dovecot-lmtp], delay=0.07, delays=0.04/0.01/0.01/0.01, dsn=5.1.1, status=bounced (host mail.example.com[private/dovecot-lmtp] said: 550 5.1.1 test@example.com User doesn't exist: test@example.com (in reply to RCPT TO command))

In the previous log example, test@example.com should have been forwarded (aliased) to the virtual mail user.

Some config details:

# From: http://wiki.dovecot.org/LDA/Postfix # Info: if you use the Dovecot LDA or LMTP it doesn't matter what you use behind the recipient address. Use "OK", the full name of the user or else. # I am using the Dovecot LMTP

@example.com OK
