PLEASE do something about the spam

And PLEASE do not reply to me with a form email. I am aware of filters, settings, etc. And no, I do not want to migrate email to a different platform or upgrade to this or that. I would like this problem to be addressed on the server end. This is NOT an end user issue as the problem started within the last several months and is persisting in spite of the best efforts of end users to establish filters, adjust DNS settings etc. PLEASE address this on the server end. Thank you.
