Hi, I've migrated my Webmin, Virtualmin and all my website from an Ubuntu 10.04 64 bit VPS server to a CentOS 6.3 64bit VPS server, using this procedure:
After that, all works well, but the Postfix server is not sending any email.
Looking into the maillog LOG file I can see:
Nov 5 16:27:27 fabio postfix/qmgr: C37A3F1B0A10: firstname.lastname@example.org, size=1282, nrcpt=1 (queue active) Nov 5 16:27:27 fabio postfix/smtp: fatal: unknown service: smtp/tcp Nov 5 16:27:28 fabio postfix/qmgr: warning: private/smtp socket: malformed response Nov 5 16:27:28 fabio postfix/qmgr: warning: transport smtp failure -- see a previous warning/fatal/panic logfile record for the problem description Nov 5 16:27:28 fabio postfix/master: warning: process /usr/libexec/postfix/smtp pid 25942 exit status 1 Nov 5 16:27:28 fabio postfix/master: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling Nov 5 16:27:28 fabio postfix/error: C37A3F1B0A10: email@example.com, firstname.lastname@example.org, relay=none, delay=420, delays=419/1/0/0.02, dsn=4.3.0, status=deferred (unknown mail transport error)
Probably the Ubuntu Postfix configuration is not compatible with CentOS configuration, but I'm not so expert to understand where...
I searched days for a solution, without success.
Thank you in advance.
PS. the new server is on the same SolusVM storage, so I don't think could be a provider problem.
