I've been having IMAP sessions "freeze" with fetchmail trying to retrieve larger e-mails, typically over 20K and always with an attachment. When I switch to POP3 I am able to retrieve the same e-mails just fine. This started at test33. I'm currently using test42 on a OpenBSD 3.5/macppc system with Maildir.

Does it happen always, or can you at least easily reproduce this? Can you save the traffic between Dovecot and fetchmail? I'd like to see that.

I guess when it's frozen Dovecot isn't actually frozen, just waiting for fetchmail to send some command (ie. uses 0% cpu and ktrace would show poll())?
