I would expect this free/open source solution to have far less overhead,
as well as having the advantage of very simple configuration, compared
with using Mimedefang.  Use a simple tool designed for the job.

I have been testing smf-sav on a couple of small systems and found it very
useful - it dramatically cut down spam on systems with no other spam
protection.  The developer is also very helpful.  I plan to use it on our
main server as soon as I have done some checks (using their very handy
sender address verification test utility) to see what addresses I need to
whitelist before rolling it out.
