Hi Gordon,

Thanks for the continued help!

AFAIK I have only used valid deliverable addresses as the FROM:. I
have been using my own addresses. I will definitely bear in mind that
it must be valid in future I had not been aware of that.

As for your other questions, I will pursue answers to those as well,
though I will probably get the admin to set up a mail account for the
script to use and switch to using Perl's Mail:Sender module under AUTH.
If problems persist then we can be pretty sure we have a blacklisting
issue I think.

Strange that in six years of using this method I have never been so
stymied by it before.

Anyway, I really do appreciate your time and advice!!

Peace,

jg
