I agree that the MX should be discriminating about what it accepts.

Many versions of evolution/Fedora ago, I stopped using junk filtering
because spamassasin was so slow and memory was a terrible issue. I
gather that the response was to implement the bogo-filter instead of
spamassassin at the evolution level to solve that but I do have junk
filtering on my mail server so I just shut it off and have left it off.
