Hi A few days ago there was an issue with one of our mail servers - and I had to disable perl related filters (dkim and amavisd). And since then it's not processing virtual_user_aliases.
in postconf -n postconf -n | grep virtual_user_aliases virtual_alias_maps = hash:/etc/postfix/virtual_user_aliases, proxy:mysql:/etc/postfix/Mail-Alias.cf And if I use postalias, I get the correct result: postalias -q p...@example.co.uk /etc/postfix/virtual_user_aliases p...@example.com but in the logs: May 27 23:30:15 mail postfix/smtpd[16493]: Anonymous TLS connection established from c62.cesmail.net[216.154.195.54]: TLSv1 with cipher RC4-SHA (128/128 bits) May 27 23:30:16 mail policyd-spf[16496]: None; identity=helo; client-ip=216.154.195.54; helo=c62.cesmail.net; envelope-from=si...@example.net; receiver=p...@example.co.uk May 27 23:30:16 mail policyd-spf[16496]: Pass; identity=mailfrom; client-ip=216.154.195.54; helo=c62.cesmail.net; envelope-from=si...@example.net; receiver=p...@example.co .uk May 27 23:30:16 mail postfix-policyd: rcpt=764, greylist=update, host=216.154.195.54 (c62.cesmail.net), from=si...@example.net, to=p...@example.co.uk, size=717 May 27 23:30:16 mail postfix-policyd: rcpt=764, throttle=update(a), host=216.154.195.54, from=si...@example.net, to=p...@example.co.uk, size=717/10240000, quota=1432/25000 0000, count=2/512(3), rcpt=2/3600(3), threshold=0%|0%|0% May 27 23:30:16 mail postfix-policyd: rcpt=764, throttle_rcpt=update(a), host=216.154.195.54, from=si...@example.net, to=p...@example.co.uk, count=2/128(1293), threshold=0 % May 27 23:30:16 mail postfix/smtpd[16493]: 57FF6C8C033: client=c62.cesmail.net[216.154.195.54] May 27 23:30:17 mail postfix/cleanup[16712]: 57FF6C8C033: message-id=<20130528013014.tc0sl3txwo4gwc88-ylqv...@webmail.cesmail.net> May 27 23:30:17 mail postfix/qmgr[16323]: 57FF6C8C033: from=<si...@example.net>, size=1209, nrcpt=1 (queue active) May 27 23:30:17 mail dovecot: deliver(p...@example.co.uk): msgid=<20130528013014.tc0sl3txwo4gwc88-ylqv...@webmail.cesmail.net>: si...@example.net: saved mail to INBOX May 27 23:30:17 mail postfix/pipe[16721]: 57FF6C8C033: to=<p...@example.co.uk>, relay=dovecot, delay=2, delays=2/0/0/0.05, dsn=2.0.0, status=sent (delivered via dovecot se rvice) May 27 23:30:17 mail postfix/qmgr[16323]: 57FF6C8C033: removed normally that delivered line would mention p...@example.com and that's where Dovecot would deliver it. How can I diagnose this? Thanks. Simon
