You are saying the time the SMTP connection with 127.0.0.1:10026 to the time that the same connection is ended? And this interval includes the processing too? > > Either the content filter has a very slow SMTP implementation, or > the content filter spends a lot of time to inspect the message. > You can easily verify which it is, by looking with top or some > other performance measurement tool. > 2) Jan 30 10:02:17 av5 postfix/smtp[5441]: 95CEE226F30: to=<recei...@domain.tld>, relay=server[xxx.yyy.zzz.uuu]:25, delay=0.11, delays=0.03/0.04/0.01/0.03, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 5C7951098002) Why the time employed by the content filter to transmit the message is different to the time to turn back the message to the queue nmanager of postfix? Is it sympthom of congestion of active queue?
