BellSouth Port 25 FAQ. BellSouth only filters Port 25. If you think you have ports blocked (other than 25) check the configuration settings on your equipment or software (modem, router, firewall, or PC applications, etc). BellSouth requires authentication (through a BellSouth issued IP) to use its SMTP mail servers. You will not be able to send mail through BellSouth if you are using another ISP for access and have a non BellSouth IP. Port 25 does not effect incoming POP email so you will still be able to receive POP mail from other providers.
Important Information: As of January 2006 BellSouth also started blocking inbound Port 25 traffic on residential accounts. This will only affect customers who are running personal email servers on their residential accounts.
