I'm having a little trouble figuring this one out. I have a client that is connecting to mindspring and earthlink mail servers using port 587. The IP's are being NAT'd and there are two lists involved. The users cannot send or recieve email and are getting time out errors when they try accessing the servers.

I have attached the sections of the config of the router for this.
