Hi;

I continue to be plagued with this error:

Oct 25 10:49:18 myserver postfix/pipe[3712]: 0423257901AB: to=<foo at bar.com>, relay=dovecot, delay=109318, delays=109318/0.14/0/0.1, dsn=4.3.0, status=deferred (temporary failure

It's been a week that I've been working day and night to get this fixed.

I forgot to add this information:
