Email Trouble Shooting

  • Make sure your user name and password are all lowercase
  • Make sure you have created the email address in your control panel (cpanel).
  • Make sure your user name is the full email address. Example: username@domainname.com
  • Try changing the @ to a % or a + in your user name. Example: username%domainname.com or username+domainname.com

Still not working?

  • Change your incoming and outgoing mail servers from mail.yourdomain.com to the ip address listed in your welcome email.

Are you able to receive emails but not send?

  • If you can receive mail but aren't able to send this means one thing.....
  • Your internet provider is blocking you from using anyone's outgoing mail servers but their own. Many major ISP's are blocking outgoing emails. The reason they do this is to prevent you from using their internet connection for spamming purposes. You will still be able to send emails, but only by using your ISP's outgoing mail server. Every ISP's outgoing mail address is different, but for the most part they will be mail.yourispname.com For example, if your ISP is AOL.com, their outgoing mail server would look like this: mail.aol.com If mail.yourisp.com does not work and you are still unable to send emails, you will need to call your internet service provider to find out what their outgoing mail server is.


We also have exim (the email handling program) running on port 26 for the above very reason. A possible work around is to change your outgoing mail port to 26 (the normal outgoing port is 25)

Are you able to send emails but not receive?

  • Either your domain is out of disk space, or your e-mail address itself is full (out of space). You will need to increase the amount of disk space or delete email stored on the server to receive mail again.
  • Make sure the incoming mail port is set to 110.

Does it say "please enter your username and password for the following server" and you are sure you're using the correct information?

  • Most of our servers have a 100 checks per hour limit, this is prevent the server from being used by spammers. If you hit this limit in any hour you'll be locked out for the rest of the hour. You will need to change how often your email client checks for email (a good start is every 30 to 45 minutes). You could disable the client from checking automatically, checking only when you want (manually).  If you do not want to disable it just set it to check less often. Keep in mind the more users you have auto checking or checking email the quicker you will hit this limit.
