cannot receive email from outside of local network
Please help, this is driving me crazy. I am using ubuntu and have it configured with the perfect setup. when i am on my network i can send and receive email fine off my server. i can use the fqdn or ip to connect and get the mail. when i am at a remote location and i connect through the internet i can send mail but when it tries to log in to receive i get:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mail', Server: 'mail.phatdawg.kicks-ass.net', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F
i can ssh to my server through the fqdn and ip. and i can also telnet to port 25, both from the remote internet.
i am fairly new at this and was doing well up to this point. any help i would be grateful.. thanks
