Earthlink doesn't block any port. However, earthlink filters outgoing port 25. It means that you have to use their email server as the SMTP authentication. If you host an eamil server, you have to use it as a smart host.
cspeye might be lucky though. but earthlink DOES filter my outgoing port 25. My zip code is 11209. |
