CentOS Server with WHM/cPanel control panel - email is not beeing sent out

[titel]

Hello,

I'm running a small hosting VPS with CentOS and I have installed the WHM/cPanel control panel.

The problem is that the email, either sent from the cPanel webmail or other client like Outlook does not get sent out with no visible error message on the client side.

Are there any log files I should check out? Is there any way I could find what the problem is?

I looked at the EXIM log and everything seems OK there; I've sent some test emails and it says they were delivered... however the emails are not reaching their destination

Thanks in advance for your answer,
Constantin TOVISI

Yes, you can check the exim logs file for the exact error message. You can check it from /var/log/exim_mainlog. Is there any bounce back email are you receiving?
