I did some testing and was able to duplicate the problem with a 32k file! I took an email with a bitmap attachment and mangled the attachment to get a message file of various sizes. For each test, I restarted iptables and restarted Outlook Express. When I got the message down to 28K, it finally went through. So 28K works and 32K doesn't work. I have duplicated this problem in the past with Thunderbird, so I don't think this is an OE problem.
