>From what I understand from these posts: http://marc.info/?l=postfix-users&m=117199107216689 http://marc.info/?l=postfix-users&m=118582818426445 your active queue is overloaded. If this is the case, this often is a result of messages coming in faster than they are going out (quite often due to the amount of time it takes to scan messages). I think you have been fighting this same problem for years now, as a number of others have too. Essentially, from: http://www.postfix.org/QSHAPE_README.html#active_queue "Congestion occurs in the active queue when one or more destinations drain slower than the corresponding message input rate." I would start by looking at some TIMING data ($log_level = 2;) to see how much time amavis spends on various functions (very likely spamassassin is where the most time is spent). If it is spamassassin, I would next break down exactly what SA is spending the most time on. http://marc.info/?l=amavis-user&m=120284838504641 http://marc.info/?l=amavis-user&m=118799923325417 http://marc.info/?l=amavis-user&m=120283445607760 This happens frequently.
