exim problem from cpanel update?

[ryonckc]

I suddenly have alot of problems from the cpanel update.

Tons of users complained about outgoing (smtp) e-mail server internal error "503 valid rcpt command must precede data"

What is cpanel team doing?!

You need to do more work investigating the problem. Look in your exim_mainlog when someone sends an email and watch for messages/errors.

If you want to escalate a problem to cPanel you have to contact your cPanel license provider.
