I once had a similar problem that was being caused by version 3.0x of Symantec's Antivirus/Filtering software which ran on Exchange. Our Windows users had no problems receiving mail but our Mac users ran into a problem where a message that was flagged as spam and had its body replaced was incorrectly being terminated.
The user would get all messages up to the offending one but couldn't get past it. The only solution at the time was to delete the offending message using Outlook Web Access or log in using MAPI on a PC. Symantec has since corrected the problem. ------- Excerpt from Symantec's Knowledge Base -------- POP3 session hangs while retrieving mail Symptom: A POP3 mail client (for example, Outlook Express) stops responding while retrieving one or more messages that were modified by Symantec AntiVirus/Filtering for Microsoft Exchange with a text substitution. This problem only affects single-part MIME messages formatted as HTML or RTF. Microsoft Outlook and Outlook Express cannot send messages in this format, so the problem is only seen in mail sent with other mail clients. Solution: POP3 messages must end with a period (.) on a new line. When Symantec AntiVirus/Filtering for Microsoft Exchange replaces an attachment or message body, it appends a carriage return (CR) to the substituted text. However, if the source format of the message was HTML or RTF, Symantec AntiVirus/Filtering for Microsoft Exchange was converting the CR to for HTML or /par for RTF. This caused the message to hang when retrieved with a POP3 mail client, because the final period (.) was no longer on a new line. The code was fixed to add the CR after the message is converted to HTML or RTF. This ensures that the final period (.) is on a new line.

I opened up my email client at home the other day and noticed that it was continually downloading the same messages over and over again. It would get to the same message each time and the POP server would stop responding and those messages were not removed from the server. So, several minutes later the cycle would repeat. I called Comcast tech support and they said that I must have a corrupted email on the server. The solution was to login with the web-based mail utility and delete the offending message. I never did figure out which message was the culprit so I deleted all of them. This has resolved the problem but I can't figure out what would have caused the problem to begin with. What sort of 'corruption' could occur to an email that would cause this sort of behavior?
