dovecot - Jun 2011 - LMTP returncode 450?

Hi,

How do I get the LMTP-server to know which mailbox's are locally hosted 
and return SMTP code 450 if delivery is attempted to a non local user?

I can see that a lookup in the userdb is done, but now matter what I 
return (1/111) from my checkpassword script I just get:

451 4.3.0 <lp at domain.tld> Internal error occurred. Refer to server log 
for more information.

You can't, at least that way. Why are you trying to deliver mails to a
non-local mailbox? You could anyway use Dovecot as LMTP proxy to the
remote LMTP server and it would deliver the mail there without an error.

Set lmtp_proxy=yes and have passdb lookup return proxy=y and
host=1.2.3.4.
