POP3 Attachments

[Owen C. Creger]

Firewall:
Fedora Core 1
iptables 1.2.9-1.0

I am having trouble with email clients on the LAN being able to recieve
emails with attachments.  Attachment size doesn't matter.  The email
clients will just time out trying to recieve an email that has an
attachmentThe firewall is able to get emails with attachements using
Fetchmail from the same server, so I don't think it is a POP3 server
issue, and everything else works fine, browsing, ftp etc...

I'm using fwbuilder 2.0 to configure iptables.

I'm sure it's something simple...
iptables -L output:
