server not sending emails
Answered
My server is not sending me emails of notifications like backups and so on.
Also it is not sending email setup instructions to customers domain names after they have created an new email account to send them there credentials.
I could use a little help on this matter.
Thank you for your time.

Hey there! Does a standard email sent from a cPanel email account work? If not, that would at least narrow things down to the notification system.
I would recommend running this command while you perform the creation of an email account:
tail -f /var/log/exim_mainlog
so you can watch that log in real-time and see if that shows anything helpful.

Thanks for that information, although those don't look like they would be related to this issue. Are yous ending from the timesheet, tourism, or audio user when you do this test? Do you see any errors in the interface when you try and send?
Does a normal email from the webmail interface work?

My server provider found that the ip address are being blocked so they are issuing me new ones.
The issue is that the emails are being blocked:

I'm glad to hear the host was able to help with this!

Wouldn't surprise me if Proofpoint was blocking your server because it has missing rDNS (reverse DNS). Good luck with your provider issuing you new ones. You will want to make sure that any IP address sending mail has a reverse DNS entry in place.
