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
virt...@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=<t...@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
<t...@example.com> User doesn't exist: t...@example.com (in reply to
RCPT TO command))
In the previous log example, t...@example.com should have been forwarded
(aliased) to the virtual mail user.
Some config details:
[root@hostname postfix]# cat /etc/postfix/virtual
