Magnus has probably put more 'thought' into it. I am just way *older*, have
done things in more different ways, and - for sure - made more *mistakes* than
most others. Wish I could say I had learned from all of them.

Seriously - you are trying to do a thing I wouldn't do at all.
On our 'under-the radar' MX here (Swiss or even third-world .tlds) we get
near-zero spam/malcode.
On really old and high-visibility domain.tld's (.com/.org/.net), some days as
much as 95% of arrivals are garbage - mostly dictionery attacks and other
WinZombies. Waves and waves of 'em.
Still yet, even on those on peak days, we call SpamAssassin for less than 15% of
all offered traffic. 12-month average is 11%, most recent Exim acl set is
dropping that to around 5%. (Worst offenders are going into IP blocklists).
The rest is shot down with Exim's DNS and smtp protocol enforcement, i.e failure
of forward/reverse DNS lookup, failed recipient verification, found in
dynamic-IP or other RBL, HELO as us, forged HELO as yahhoo, et al, found in our
own 'brownlists' built from repeat-offender scoring in SQL DB, etc.
By scoring only when several violations have been committed, or a tell-tale
'pattern', very few false-positives arise, and can be easily 'whitelisted' if
need be.
So - Exim is capable of onpassing such 'clean' traffic that you would not need
any further filtering. Shuttign down spamd would hardly make a bump in our
user's 'Inbox', only in their quarantine folders.
Nor do you necessasrily even those other mx for distribution.....
...unless, for example, you 'need' Exchange for its non-mail group-working features.
