There are no updates yet, none good anyways. We have tried to completely re-install the mailserver from scratch, we have removed the antivirus and tried another reinstall. We have copied config files from other working mail servers, but exim is still complaining of a bad configuration file.

We are about out of ideas here in a few the entire machine will likely be rebooted to see if it cures the issue and if that fails all we can do is wait for a cPanel dev to check it out.
