Not that I'd ever outright block based on this one factor alone, but...
Does anyone have any stats about what percentage of spam is directed towards
the highest MX Record? (that is, where there is more than one MX record?)
Our lowest priority MX is just a store and forward box left over from
when backup MXs were useful. We only keep it around because a few
(getting fewer) clients say the PC magazine pundits say you need one. So
they pay.
We do all the normal user validation, greylisting, RBLs, same as our
other servers but the spammers insist on using it.
Here are the stats for yesterday;
total messages total viruses total spam
-------------------------------------------
120,242 1,681 106,102
Also, has anyone ever seen ANY legit mail go to the highest MX record when
no mail server failure occurred?
Just about any MS Exchange server. I have never had a valid message from
qmail/Sendmail/Postfix/Exim go to that server. Always Exchange, and
generally from a small business with a "shrink wrap admin" running the
mail services.

Three years now I've asked Google why they don't have a
logo change for Memorial Day. Why do they choose to do logos
for other non-international holidays, but nothing for
Veterans?
Maybe they forgot who made that choice possible.
