Sending Mail through outlook or outlook express fails

This problem occurs usually due to the mail client — e.g. MS Outlook or Outlook Express. So please check these following issues and make sure it is correctly set up.

1. The incoming mail server needs to be typed correctly.
Solution: Go to Tools > Accounts > Mail > Properties > Servers
Change the incoming server (POP3) to: ‘’

2. The POP3 account name as well as the POP3 password needs to be typed correctly.
Solution: Go to Tools > Accounts > Mail > Properties > Servers
Retype both the account name and the password.

The primary account username will be ‘username’. But if you’ve created an alternative e-mail using your cPanel then the username for the POP3 mail server will be ‘’

3. It may be that POP3 is using the wrong port number.
Solution: Go to Tools > Accounts > Mail > Properties > Advanced.
Change the incoming server (POP3) port number to 110.

4. Check whether Outlook Express is trying to use SSL:
Solution: Go to Tools > Accounts > Mail > Properties > Advanced
Uncheck the option to use Secure (SSL).

5. Outlook Express may be set up to use Secure Password Authentication.
Solution: Go to Tools > Accounts > Mail (tab at the top of the new window) > Double click on the e-mail account you set up > Click on Servers (tab at the top of the new window) > Put a check in the box that says “My server requires authentication”.

6. Check whether mail servers are set correctly.
Your mail servers needs to be set as follows:


7. Remove and recreate the e-mail account through your cPanel control panel and see if it works.

If this does not work, it is possible that your ISP is blocking outside e-mail servers so that you must use their outgoing e-mail servers. This is done by the ISP in an effort to block SPAM. MindSpring and AT&T are known to be ISPs which do this. If your ISP has blocked outgoing e-mail servers, you can use the Web Mail feature in your cPanel to send/receive e-mail.

If you tried all the above steps and you still get an error, then do this simple test. In Windows, hit the START button and click on RUN.
In the command bar, type this: telnet 25

Observe the results. If you get this: ESMTP Exim 3.36 #1 Mon, 9 Feb 2004 14:20:15 -0500
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.

That means you can connect.

However, if you cannot, that means your ISP has blocked it and is forcing you to send e-mails through their ISP’s e-mail servers instead. In this case, nothing can be done from our side. You will need to contact your ISP and ask them to give you the outoging mail server settings.
