| Subject: | Postfix/ClamAV Config Error |
| Group: | Postfix-users |
| From: | Garth Keesler |
| Date: | 28 Nov 2007 |
I've been working my way thru the building of a Postfix SMTP relay
following the steps in several books I purchased as well as various
HowTo's on the web. I have PF successfully installed with SpamAssassin
working and the relay doing very restricted forwarding of SMTP email
into my Exchange server. Prob is, whenever I try to bring ClamAV into
the mix I invariably get the following error:
Nov 28 13:29:40 mail1 postfix/master[5152]: fatal: bind 127.0.0.1 port
10026: Address already in use
The box also stops accepting telnet 25 connections as soon as I load
this config. If I roll back to a non-ClamAV config, all starts working
again.
Below are sanitized main.cf and master.cf for your perusal.

I'm getting close (I think:-) so any help would be greatly appreciated.
