Troubleshooting


Common error #1:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ‘ (recipient) '. Subject ' (subject) ', Account: ' (sender) ', Server: 'smtp.nucleus.com', Protocol: SMTP, Server Response: '501 This system is not configured to relay mail from < (sender) > to < (recipient) > for (IP address) ', Port: 25, Secure(SSL): No, Server Error: 501, Error Number: 0x800CCC79

Outlook Express

  • Click on "Tools" >"Accounts"
  • Click on the "mail" tab
  • Double click on your Nucleus email account (if you have more than one, you will need to duplicate steps 4-8 for all the Nucleus email accounts that you have)
  • Click on the "servers" tab
  • Make sure the Outgoing Server (SMTP) is set to: smtp.nucleus.com
  • Make sure the account name field has your FULL email address in there
  • At the very bottom of the "servers" screen, make sure there IS a checkmark in the area that says "My server requires authentication"
  • Click on "OK" and then click on "Close." You're done!

Outlook XP or higher

  • Click on "Tools" > "Email Accounts"
  • Click on "View/change existing email accounts"
  • Double click on your Nucleus email account (if you have more than one, you will need to duplicate steps 4-8 for all the Nucleus email accounts that you have)
  • Make sure the outgoing mail server (SMTP) is set to: smtp.nucleus.com
  • Make sure the "user name" field has your FULL email address in there
  • Click on the "more settings" button and then the "Outgoing server" tab
  • Put a checkmark in where it says "My outgoing server requires authentication"
  • Click "OK", then click "next", then click "finish". You're done!

Common error #2:

"The operation timed out waiting for a response from the outgoing/incoming mail server"

This error message is typically generated when your connection is working fine, but something is blocking access to the mail server. If your Internet connection is working okay, simply try rebooting the computer. Failing that, if you are running "Norton Anti Virus", "AVG" or "Zone Alarm", try disabling them altogether. Those programs can interfere with proper connections to our mail server by inadvertently blocking the port that we use to check or send email.

Common error #3:

"Cannot find host: (incoming/outgoing mail servers) "

To solve this problem, double check to make sure your Internet connection is working at all by attempting to view web pages. If not, we are dealing with a totally separate problem and you will want to start troubleshooting your entire connection as opposed to just your email program. If your Internet connection is working fine, double check your email settings under the "Tools > Accounts/Email Accounts" menu.
