Thanks for answering. The timeouts happened because postfix was waiting for opendkim. Changing the socket from tcp to unix domainsockets solved this, almost: at busy moments postfix now logs: telemann postfix-13/smtpd[28087]: warning: connect to Milter service unix:/var/run/opendkim/opendkim.sock: Resource temporarily unavailable And opendkim says: opendkim[3963]: OpenDKIM Filter: accept() returned invalid socket (Numerical result out of range), try again Is postfix requesting something invalid, or is this a problem with opendkim?

Re: Timeouts when submitting mail
svdr: > What can I do to find the reason for the timeouts? You need to find out where in the SMTP protocol the timeout happens. - TCP connection setup. - SMTP Server '220' initial response. - EHLO, MAIL FROM, RCPT TO, DATA, end-of-data. Ideally, the PHP client would provide that information. Postfix logging will show 'lost connection after XXX', but that happens only for a completed TCP connection. Wietse
Timeouts when submitting mail
We've set up two servers (ssd raid/64GB/fast dual cpu) with postmulti to deliver the mail for our newsletter service (legitimate mail). Both servers have 12 postfix instances running. Mails is injected from php scripts running at a different server. Lately we're seeing timeouts from the php scripts at busy moments. I've been trying to debug this, but can't find the issue. Some information: - Mail is injected through smtp, port 25 - The active queue is almost empty, even at peak moments (qshape) - Number of deferred mails is low - I've set default_process_limit to 1 and smtpd_client_connection_count_limit to 3000 - Load on the servers is never higher then 2 - Number of smtp processes peaks at about 2000 - We're running local DNS - We're using opendkim to sign every message What can I do to find the reason for the timeouts? Thanks. -- View this message in context: http://postfix.1071664.n5.nabble.com/Timeouts-when-submitting-mail-tp91116.html Sent from the Postfix Users mailing list archive at Nabble.com.
