We’ve updated Virtualmin and individual packages quite a few times in recent months / years and somewhere along the way, we started seeing UNCHECKED added to the beginning of every subject line in the recipient’s email. This is happening for all domains on the Virtualmin server. It started a few months ago. I’ve searched and found some similar threads, but the solutions for those were either adding memory (our server is not showing a need for that and the dashboard is showing we regularly stay between 50-60% of real memory) or completely disabling virus filtering in the server features (I’ve done that). Can someone suggest how to further troubleshoot?
***UNCHECKED*** subject in all emails
