Yeah ... for some reason I forgot to change the address before sending
this reply. :)

But I can see now that this might be of general interest, so I'll keep
my response in this list.

Perhaps that was your intent all along. Nice try Buddy!  <g>

Ah ... I get it now.  When you write "checked", you mean checked via
SPF.

Out of curiosity, what is the general consensus as to the value of
rejecting mail with non-valid hostnames in the HELO string?

In my view, a high value.  But you have to watch for backward compatibilty.
In other words, if the clients attempts to use a valid formatted client
domain name, then that your trigger to perform a check.

If a legit systems fails, trust me, they will complain. You will hear from
them.   But don't expect the "Spammer" to call you up to complain about it.
