Emails in logs all say recipient unknown
Yesterday, we uninstalled ConfigServer software from our cPanel, and installed Imunify360. We used the uninstall/install scripts via terminal. Now, recipient emails are all saying "unknown" and most of the From Addresses are saying [system] when I check on the WHM mail logs.
I know for a fact that the majority of the messages in this screenshot are from my email (not hosted on the cPanel) as a test to various client emails on different cPanel accounts on the server.
However, in the cPanel mail logs in the individual accounts, the messages I have sent don't appear at all.
Clients are finding that when sending messages through the server, the messages successfully go into their "sent" folder and there are no error messages. But they are never received. And incoming messages aren't being received either - there are a very few spam messages showing up in the mail logs on individual servers. (blocked due to RBL etc)
Something has gone terribly wrong in the uninstall of ConfigServer softwares and install of Imunify.

Hey there! This is likely an issue that would be better handled through a ticket since it seems to affect the firewall, Imunify, and mail delivery, and I just don't think trying to troubleshoot all of those areas in tandem over the Forum is going to be effective.
