more fun with iptables

Hello all,

Yesterday I posted asking about my iptables policy, you can see that thread here

The use of that policy with the listed change produces errors with email on the server. In short, email bounces to the server. A bounce looks similar to this

Code: 
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

address@domain.tld
local delivery failed

------ address@domain.tld ------

An error was detected while processing a file of BSMTP input.
The error message was:

421 SMTP incoming data timeout - message abandoned

The SMTP transaction started in line 0.
The error was detected in line 3.
0 previous messages were successfully processed.
The rest of the batch was abandoned.
421 SMTP incoming data timeout - message abandoned
Transaction started in line 0
Error detected in line 3

------ This is a copy of the message, including all the headers. ------

Return-path: 
Received: from [4.7.28.249] (helo=gaia.asylumgroup.net)
