Hi,
We've got a weird issue, either that or i'm just paranoid. We're running postfix 2.8.2 on one of our new filter/transport machines, this is a simple setup of postfix via lmtp to dbmail-lmtpd. All postfix does is a transport lookup in sql. This all works fine, however, postfix seems to send all of its active queue in large bursts, i.e. it will build up its active queue which will sometimes reach 1000 emails at a time and then send them all to dbmail-lmtpd (2.2.17) in one go, then it will pause (stop sending to lmtpd) for 5 minutes then it will start sending through again. I found that the 5 minute pause time in postfix I could manipulate by dropping the timeout in dbmail-lmtpd to say 60 seconds. This doesn't seem normal to me, and i'm tempted to downgrade postfix on this machine to the old stable just to see. Any thoughts?
Kind Regards
James Greig
