Hi,
Number of clients who are using Outlook and windows live email client program can’t send emails.

Getting the following error message below:

Task ' - Sending reported error (0x800CCC13) cannot connect to network...

Task ' - Sending' reported error (0x800CCC0B) : 'Unknown Error 0x800CCC0B'

They however can receive emails but not send. Mail is just stuck in outbox.

Before the cPanel update everything was working fine.

I have disabled the "Introduce a delay into the SMTP transaction for unknown hosts and messages detected as spam" option.

Please advice?

Hello :)

Are your users sending email over port 25? If so, can these users successfully telnet to your server's IP address over port 25? Are there any error messages in /var/log/maillog or /var/log/exim_mainlog when a user attempts to send an email?

Thank you.
