My assumption is that if I were to run SpamAssassin and amavisd-new on
my MX hosts -- which, BTW, are cloud servers -- this would keep junk (or
suspected junk) from tying up network bandwidth on my main system.

Please explain further.  I understand that different people disagree on
whether spam should be quarantined, or delivered after being flagged.
What are your reasons for opposing the quarantine approach?  What do
other list participants think about this?
