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?)
Also, has anyone ever seen ANY legit mail go to the highest MX record when
no mail server failure occurred?
I get lots of mail from a number of different Domino servers delivered
to my lowest preference MXes. I've always suspected it was something
IBM had done to Domino to "improve queue performance" but I've never
looked into it.
