This would not be a good thing to do, as deleted email will magically reappear. Using unison to sync it worked for me, over 10years ago. But these days, just use dsync part of dovecot, and your life will be happy. Quoting Patrick Chemla : Hi Wietse, Of

I have Postfix/postscreen 3.1.4 + AV/AS/etc. running on a hosted VM. It acts as a front-end, delivering to another postfix instance that's on my LAN; the comm's over a VPN link. The local postfix instance delivers via LMTP to an IMAP store, currently on the same box. It also provides port 587

Re: [Solved] Postfix can't send from localhost

It turns out the previous admin neglected to include a section in master.cf to indicate the relay port that was specified in the dkimproxy_in.conf file. Adding that section cured the problem. Apparently the old system running on lenny somehow tolerates the omission without causing any problems.

Reject code for overquota and non-existent virtual users

If /dev/log would not be hardcoded in syslog.h it would be possible to make the socket configurable in postfix and output directly to the rsyslog process. :-( On 2017-01-23 15:04, wie...@porcupine.org wrote: And the logging daemon uses more CPU than Postfix. We're back 20 years ago. --
