Firewall ReportAs you can see from my logs, auth is not getting through my firewall, this is slowing my mail connections down. the rule I have is ACCEPT net $FW tcp 113.

If it is Chet''s MTA (which can''t be Postfix since it doesn''t use auth) that is generating the auth request, then Chet needs: ACCEPT z net tcp a where ''z'' is as in the prior post (or he needs to disable auth per Steve''s instructions). -Tom -- Tom Eastep \ Shorewall - iptables made easy AIM: tmeastep \ http://www.shorewall.net ICQ: #60745924 \ teastep@shorewall.net
