I should have added more details here. I know this looks like a classic issue of the client app not reading its data (netscape mail polling mail over imap in this case). It's just that the same exact app was working fine on the same mail folders on non XP machines, and the same netscape had no issues polling mail from other servers, so I started suspecting something on the TCP layer between the two OSes Mika Liljeberg sent me a mail confirming that it really looks like the client app not reading its data. Of course, I can strace the imap server, but I don't know how to do that with netscape on XP :-) Either way, although I can't confirm it for now, I'll assume that something weird is happening with the app, and that it's indeed responsible for the stall. Sorry for the noise.
