We score for bad $Helo and sometimes we reject when a message has other
spammy features.  Whenever I get a report of this, it always turns out
to be some small-scale operation like a club, a church, a museum, one
guy sending newsletters, etc.  Why?  I suppose because larger places
have enough IT staff that some one of them knows how to get this right.
I end up talking with people who half the time don't know what HELO is
or how to configure it.  The other half get it fixed but act as if we
are the only place they send mail to that ever cared, which is probably
the case.
