Port 110 is for POP, which is for inbound messages. Not knowing the specifics of your setup, I would guess that your ISP is blocking port 25 to force you to use their mail server. Try using telnet from the command line to see if you can manually connect to port 25 on the mail server you are using in Mail.app. Use it like this: telnet smtp.foo.com 25 (substituting "smtp.foo.com" with the mail server you are using in Mail.app). If you get a connection, just type "quit"; if you don't get a connection, telnet will probably hang or will return "connection refused." Either of those might be an indication that your ISP is blocking port 25. Eagle
