Thanks for the lesson on this.  I have not found any reference to HELO
addressing in the rather scanty Qmail manual I have so I have attempted to
address this with the old Webmin standby.  I am always reluctant to use this
as it has caused things to break for me in the past.  Please let me know if
I have succeeded in changing to the correct HELO.

Regards,

Rick (who will go to bed shortly now that our LUG has left my premises).



Just as a general note, I had previously white-listed the Humbug
lists so that my spam filters would not catch list posts, but
the list headers changed some time ago and so my white-list did
not protect this message.  (I've updated it now to respond to
stuff that *is* in the list headers, but the issue with broken
email setups is still relevant.)

Cheers, Greg
