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.
