Hi there,

It looks like something has recently changed in the ISC DNS.

Our picky servers started blocking list mail.  Thinking it might right
itself, at first I ignored it.  Then I tweaked some filtering rules to
let list messages through.

Below is from our own DNS server; I get the same response from all the
public servers that I've tried.

mail6:~$ >>> dig -x 149.20.1.60

No problem as far as I'm concerned, I just hope whoever needs to know
about this knows about this (and that I haven't missed something. :)
