Why do we only care about the first?  I'm tempted to say, fail if ANY of

have multirecord MX's with only one of them (not the first) being 127.0.0.1?

Any MX of 127.0.0.1 is not only broken but malicious.

I remember a year or two ago there was a fad in which admins would set up a tertiary or higher MX pointing to 127.0.0.1 in order to hassle spam software that used the highest MX instead of the lowest.

I don't know how many of these are still around, and I never thought it was a good idea -- and you can definitely argue that it's a malicious config!
