Answer

If you are able to receive mail but are unable to send, your ISP is probably causing the problem. Most ISPs, especially cable and DSL providers, block port 25 which is the old standard port used to send email. They do this to try to force you to send all email through their servers so they can monitor it for things like spam or viruses or try and prevent a spammer from using their servers via a hacked PC on the ISP's network. Try changing the SMTP port setting in your mail software from 25 to 587. If that doesn't work, you can use 2525 instead. Port 2525 is a special connection we have setup on our server to bypass the ISP level blocking. Once you do this you should be able to send mail. If you are still not able to send, you will need to switch your outgoing mail server from smtp.yourdomain.com to the SMTP server your ISP provides.
