xinetd or pop3d is sending an ident request which is being blocked by a firewall - the packet being silently dropped so the originator has to wait for a timeout. I tested it here. Dropping packets to port 113 on my workstation then trying to connect to our internal pop3 server caused a long delay before the `POP3 ... ready' message appeared. Changing `DENY' to `REJECT' caused the `POP3 ... ready' message to appear immediately.
