Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B

Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B

You may receive this error in your email client settings at some point. In Outlook this is a bug and can usually be resolved by restarting your email client and making sure you have SMTP authentication enabled.

This is not a server problem and is caused by a miconfigured email client, ISP's blocking access to port 25 and using port 26 instead or a DNS problem with your ISP.

To confirm that the mail server is online and responding you can perform the following:

From the 'Start' button click 'Run'
Type in 'telnet yourdomain.com 25'
You should receive something to the effect of:

220-servername.domain.com ESMTP Exim 3.35 #1 Thu, 23 May 2002 22:31:23 -0400
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.

This confirms there are *no problems* with the SMTP server

To confirm the POP server is online and responding:

From the 'Start' button click 'Run'
Type in 'telnet yourdomain.com 110'
You should receive something to the effect of:

+OK POP3 [DarkORB cppop 1.2] at [66.197.198.81] (yourdomain.com)

This confirms the POP server is online and there are *no problems* with the POP server.
