 Email Troubleshooting

  When you try to send email you get a message that says '553 Sorry, that domain isn't in my list of allowed rcpthosts'.

99 times out of 100 this is because you don't have 'SMTP Authentication' turned on. This means your email program is not sending your username and password information and, as a result, our mailserver will not relay mail to the outside world for you. If you are using Outlook Express please see step 10 in the tutorial. The box that says 'My server requires authentication' must be checked - and only that box. Other email clients are similar.

  When you try to send email you get a message that says something like "can't connect to mailserver".

This is usually caused by your local ISP (Comcast, Verizon, AT&T, etc) blocking connections to remote mailservers. They do it primarily to stop virus infected PC's and spammers on their networks from spamming the outside world. These blocks may be temporary or permanent but they only affect your outgoing email - not the incoming.

If this happens to you you can use your local ISP's outgoing (smtp) mailserver instead of ours. Call your ISP to find out the name of the mailserver and the connection info. You can still leave the incoming (POP3 or IMAP) mailserver setting pointing to our servers so you can retrieve your email.

Typically ISP's will only block connections to outgoing (SMTP) port '25'. We have other ports available that can be used to connect to out mailservers - try port 26 and port 587.
