There are several common reasons why you may not be able to send email.

Using the wrong SMTP server or you're not on the BellSouth network
Just like other ISPs, BellSouth uses precautions to prevent relaying email through their network. Some examples:
- If you are not on the BellSouth network and don't have a BellSouth IP and try to relay email through the BellSouth SMTP server to another email domain you will be blocked. If you are travelling or on another ISP's network you can use BellSouth Webmail.
- If you have an IP assigned by BellSouth and you try to send mail using another ISP's SMTP server chances are they will block your email.
- If you have an email account with another ISP and you want to use that email name on BellSouth's SMTP it will be blocked.
- If you are using a email domain other than "bellsouth.net" you may be blocked. For example, if you use "myname@brandx.net" and try to send it through BellSouth's SMTP server it will be blocked.

Your email client is set up incorrectly or may be corrupted
For information on setting up common mail clients see the Email Configuration FAQ or the BellSouth Email Configuration Site. Many times, simply reloading the email client software or deleting the account and reconstructing it solves the issue.

Port 25 is blocked
All new residential dial and FastAccess accounts are provisioned with Port 25 blocked. All existing residential accounts will eventually be converted. For more information check the Port 25 Block FAQ or the Official BellSouth Port 25 FAQ.

Third party hardware or software is interfering or interrupting your email
Firewalls, antivirus, and other applications may change settings or block email. Turn off all suspected software and test again. Additionally, your hardware firewall or router may be configured incorrectly.
