Some ISP's will block the port that you need to use to send email.
TCP Port 25 is the default SMTP port that you use to send email and it is also the standard port all SMTP servers use to communicate.
To help curb the spam problem, some ISP's block their customers from connecting to port 25 outside of their network.
You can test this by going to a command prompt and trying to telnet into the port. In windows XP and 2000 you can get a command line by going to start-> run->typing cmd. On windows 9x you do the same except type command at the run prompt. The syntax for telnet is the following:
telnet mail.yourdomain.com 25
If you cannot connect to your mailserver then it is likely your ISP has blocked the port. Usually, if the ISP has the port blocked, they will provide you an alternative server to use to send email.
In addition we do have port 587 open on the mail server as an alternative smtp port. You can try to set your outgoing port to 587 if your ISP is blocking the default port of 25.
