I've used failed forward and reverse lookups of the HELO and MTA IP for a long time as spam indicators in Spamassassin's rules, and they *are* useful spam indicators, but I think that summarily rejecting mail on this one check is summarily bad. James, I'f you've had this absolute condition added to the IETF mail setup, then please have it removed again and let Spammassassin use these lookups as two among its hundreds of weighted checks. That seems sane to me; the current situation doesn't.
And I certainly didn't want this to escalate into something this involved.AFAIK this check has been in there since cutover, and I can't speak for why it's suddenly become exposed... but in the interest of getting a quick resolution, even if a temporary one, I've modified the ruleset here.
Eric, could you please test this and let me know how it goes? If it fails again, we can try something else.
Thanks, Glen
