Thanks, all.
My answer to the question of why: To make it slightly harder for bad

On Sun,
Anybody familiar with the Gmail headers X-Gm-Message-State and
X-Google-Smtp-Source? A coworker asked about them, but I am not really
familiar. Figured I'd see here if anybody knows anything about them.
Thanks in advance for your thoughts or feedback!
Cheers,
Al

archive, if you like.
I've seen it happen perhaps twice in twenty years, from what I can
non-scientifically recall. 99.9% of the time we've had somebody
complain they can't find the mail in their Gmail account, it is
because it's in their spam folder. I'm not particularly worried that
there's some new outbreak of th
