From: "Sasa" on 17 Mar 2010 06:45 Hi, I have a smtp/pop3 public mail server, this server is in production enviroment form 3/4 years nobody problems but from two days I have sometimes that smtpd not responding and I have this error:: 2B85826A5B3 8913 Tue Mar 16 16:41:11 listbounces2(a)domain.eu (delivery temporarily suspended: conversation with 127.0.0.1[127.0.0.1] timed out while receiving the initial server greeting) xyz(a)domain.biz and all mails keep in queue. Then I must restart postfix and amavis services and after the mail are delivered. This problem can be generated by a few hardware resources available or can be a problem caused from postfix or amavis ? I use: postfix-2.5.6-1 Thanks. ------ Salvatore.

Thus, reduce the process limit on the Postfix side (in master.cf) or increase it on the amavisd-new side, if sufficient memory and other resources are available. Wietse
From: "Sasa" on 17 Mar 2010 09:23 I have modified the value of: $max_servers=10 --> (from 2 to 10) and maxproc in master.cf smtp-amavis unix - - n - 5 smtp --> (from 2 to 5) now I must: #postsuper -r ALL #postfix flush for to use a new parameter and for requeue the postfix queue ? sorry for my banal question, but into what syslog file I must view ?
