Should show. Usually this setuid flag is removed on a simple copy process for a good reason

chmod +s `which sendmail`

Sets this flag - of course if you really run Sendmail and not use another MTA like Postfix / Exim / Qmail.

And finally check if all Groups / Users are present with:

getent passwd
getent group

Just in case something is missing there.

Simple check if everything is working can be done while tail'ing the mail log:

tail -f /var/log/mail.err (if that's the file)

And on another console mail'ing yourself:

mail -s Test myownmailaddress@anotherdomain.com

Then some text, a Ctrl+D ends the editor and sends out the mail. This should give you some more info what could be wrong.

Ok seeing as you know everything, what email program does a cpanel server use, i'll give you a hint its not sendmail.

As stated in my first post, tail the exim_mainlog, you will find nothing in the maillog file.
