A legitimate MTA could still be running in a dynamically-assigned space.
In this case it might hop all over the space but probably wouldn't hop
very frequently.

A single MTA host might have multiple NICs each with its own IP, and not
always choose the same interface for the same MX on retry.  Here it might
hop quite a lot, but among a limited number of choices.
