Connection Closed/Cannot Sync error - Netscape (AOL) mail

[egf]

I just installed Zimbra Desktop and it will not sync completely with my Netscape.net e-mail account: it starts and works for a little bit, then closes the connection and sends the error message. I've searched the forum, but most of the Netscape related material is very, very old. I've attached the debug log (it's fairly long), and hope that you can help.

Just FYI, I've had problems with other e-mail clients and Netscape, so it's probably something on their end (and they are not the least bit helpful!).

Thanks!
