am not running a virus software coz i new this would coz a lot of delay its only qmail-scanner running, if someone is sending a large mail lets say over 40mb can it coz qmail-scanner to slow down Jason Haar wrote: On Thu, Oct 30, 2003 at 02:32:18PM +0300, Maxwell Ochieng wrote: my mail server sends more 15000 mails everyday and since i installed qmail-scanner mail delivery has realy slowed mails delivery. I would expect it to slow down "a bit"... my server does not have any filtering/quota on the size of mail to send can this be whats affecting mail delivery since sometimes i see qmail-scanner takes even around 700secs to scan one e-mail. OK - 700 secs? That's not normal :-) What must be happening is that you have a major bottleneck in one of the things Q-S does, and that leads to a spiraling problem that more and more mail queues up behind this bottleneck - leading to misery all 'round. So: where is the bottleneck? Check qmail-queue.log - what does it tell you? You will see that I have specifically put timestamps recording how long each primary subroutine takes to run - so you should see that (say): 1. message writing to disk in 0.2 sec 2. message unpacked into bits in 0.3 sec 3. virus scanner runs over bits in.... 600 secs 4. message delivered in 0.1 sec So the bottleneck is "3". What does your logs tell you?
