Does it time out eventually, i.e. after 10 minutes? If not that in itself
could be considered a bug.

The question is how pop3d knows that the connection is dropped. And maybe
that's really where dial-up comes into play. In don't know if you're in a

dial-up and then drop the dial-up connection? I guess I might try that from
