SUMMARY

When retrieving email via POP, some client configurations will timeout on specific messages.

DETAIL

This can occur if the message being downloading is malformed, and the client computer has anti-virus or anti-spam software running (such as McAfee or Norton Anti-virus). The software installed on the client has problems with interpreting the email and does not finish, and does not try to download the next message from the server.

To resolve, the anti-spam or anti-virus software has to be disabled if not at least to diagnose and debug.  In some cases a single message could be holding up the download on the client firewall end, once this message is removed or let through by disabling as previously mentioned every thing can be resumed as per the previous configuration settings.
