Hello: Recently elected to install clamAV via WHM/Cpanel on our server. Seemed to work fine, ran a bunch of scans on various domains hosted on our server (via Cpanel), cleaned out a bunch of phish files and trojans. However, today I started getting this error in Outlook whenever attempting to send an email: I've been researching this throughout the web. I see a lot of threads but no definitive fix for it. Many of the other posts pertain to an error regarding one or more of the 'recipients' but mine is stating the server is rejecting it. This leads me to believe that it's checking against some list that is blocking my domain. WHY I don't know. Unless it has some method of determining if an email is spam and adding it automatically to some blocked list. Also, the other accounts we host on the server are not able to send or receive. This is a mess. Using clamAV .88.5 Any help would be greatly appreciated!
