Hi all, I am having little bit of problem with delivery. I had postfix+mysql+dovecot+amavisd-new all in one machine. It was working fine but I just wanted separate those components so I tried to offload amavisd-new first. After one day of separating it, i see a lot of messages in the active queues and deferred queues and it is delaying the message delivery. I see a lot of messages has 'Connection timed out' in deferred queue. I would like to know what I can do to correct this problem? I have a feeling that this is related to configuration of my number of smtp, smtpd, amavis processes. Can someone help me?? Thank you, Justin
