Thanks, that is more helpful. The mail size is 4.9 MB, and it takes 1.4 minutes to process on one host, and 3.7 minutes on the other. It contains a RAR archive, so although the processing time is not small, it is not unreasonable for such a long message. About 90% of processing time is spent in AV checker, which again is not unreasonable, considering that this RAR archive expands to 34 MB. The 3.7 minutes is well below 8 minutes of $child_timeout, so amavisd does not time out on this message. If MTA times out with waiting earlier than in 3.7 minutes, you end up with mail message being send, one copy at every attempt: amavisd successfully processes and forwards the message in time, yet MTA gives up earlier, telling the client it hit a temporary failure and that it should re-try later. Fix MTA timeout, it should not give up sooner than $child_timeout time, customarily MTA timeout is set to 20 minutes. Don't know how to set this timeout value\ on qmail.
