Yes I saw it before :-(
I' having the same problem and not only with pop3, but also when sending an
email with an attachment.
The transfer of the attach begin an the server send out a fin packet and
drop the connection, sometimes happens immediatly sometimes after a little
transfer.
I saw it with outlook and outlook express, the mail server is behind a linux
firewall. I made alot of investigation about this problem and it dont seem a
network problem implicable to the firewall.
If you find a solution please let me know.
