Interesting. Good stuff to know.

I read it has a incoming and outgoing queue.

What are some of the drawbacks of the two? What can Mailscanner do that
MIMEDefang cannot? And vice versa?
Is one more secure than the other? What about stability? Reliability?

I see. So it could be dependent upon how much email is sent and received daily.

Anybody else care to comment on this?
I'd love to hear more feedback. Makes my decision easier to make.
