Unable to get sender domain by sender mailname

[VinceP]

I'm running Plesk 12.5.30 on Centos and have the following messages on my maillog which leads me to believe that one of the domains that I have hosted isn't sending out mail correctly.

How can I find out which domain it is or how do I fix these errors?

I've tried # plesk repair mail and also made sure that 127.0.0.0 / 8 and ::1 / 128 are in the whitelist but I'm still receiving the messages
