Since I've had home ADSL from Earthlink, I have been running a small SMTP server, and it worked fine (I use it with my own domain name). However, since about a month ago, they blocked port 25 and I can no longer receive any e-mail to the server. They do say that I can run whatever server I want, just that they block port 25 now.

Does anyone know a free alternative I can use, in which I can still use my domain, and especially if I can still use my own mail server? (Like port fowarding or something..?)

Thanks
