I cannot send email through my domain, what is causing the problem?
There are generally two things that will cause this problem. First, our Spam Control is turned on, and your ISP is not on the list of approved ISPs to send e-mail through our SMTP servers. Please contact support@mitchellmedia.com to get your ISP on the list of authorized port 25 connections. Second, sometimes ISP’s will block all port 25 traffic so they can control SPAM going through their system. In other words, some ISPs require that their users use their SMTP server to send out e-mail. Port 25 is the common port that is used for SMTP service on Internet servers. There are many large dial-up ISP’s that do this, Concentric would be a good example. You will need to check with your dial up provider for more info. If you are in a situation where they are blocking port 25, for your SMTP setting just use the one your local ISP provided.
