Hey guys just wanted to bounce this off the list and see if anybody else has seen this issue or know of a fix. We run 4 qpsmtpd servers all load balanced using ultra monkey, linux ha basically, and lately I am getting alot of bounces due to things such as:
>>> HELO imo-m27.mx.aol.com <<< 500 Unrecognized command >>> QUIT <<< 500 Unrecognized command >>> HELO imo-m14.mx.aol.com <<< 503 MAIL FIRST < mail33-red-R.bigfish.com #5.0.0 X-Postfix, host mx.highspd.net[208.62.90.253] refused to talk to me: 503 MAIL first> These are just a few examples, but I am getting probably 5 complaints a day about bounces with the same messages. Anybody have a clue about what is going on? On a side note, is it normal to only be able to get 20-25 connections per machine? Our machines are spec'd as follows: P4 3.0Ghz, 1GB Ram, 40GB ATA 133 Running: FC 2, SpamAssassin 3.0, ClamAV 0.80, qpsmtpd 0.29 SA is running with 13 .cf files including bigevil. At 25 connections we starting hitting a load of 1.5 - 2.0. If that's normal it's cool, if not what might I be doing wrong? Thanks in advance everybody. Ed McLain High Speed Solutions
