Yummy, though I'd be somewhat concerned about environments placing their
outbound mailservers behind NAT firewalls.  Still, the proportion of
servers both (a) doing that and (b) issuing IP HELOs is probably
vanishingly small.

I've seen excite.com also, so you might consider adding that.

Ask, Mark has pretty well superceded my original check_spamhelo with
this, so once this is adequately tested I suggest deprecating or
replacing mine in favor of this one.
