Hi! I was receiving emails with no content. No sender, no subject, no message. When I disabled the pickup event at the Mail Transport Agent, that executes this file mailfilter.exe, I resolved that problem. After turning off the pickup event I can receive emails with content. This mailfilter.exe was removing content from my emails. What does this file do? What will I miss if I turn it off? I'm thinking of using another file in it's place that will block certain file extensions. Thank you.
