So, it might be useful to figure out exactly what is causing the spam
tagging, and work on that.  I know that this is sometimes hard to

I can only say that this email has one domain, but is being submitted
to another domain and AFAIK, I get caught in zero spam filters ... at
least, that's what I can tell.

Well, I guess I would wonder what the effects of that are.  First off,
I see your message-id has "@localhost.localdomain" in it; if I had to
guess, I would think that would be one of the biggest things that
spam filters are being triggered by in your case.  Also ... I don't
understand why you would need to do this to stop email bounces.  Your
bounces should be going to the envelope-from address, and that looks like
it is set correctly.

So my configuration is that I do not use sendmail at all; I have nmh do
authenticated SMTP directly to the mail server I send stuff through.  I
think that if you did that you'd be in much better shape; for starters,
your message-id would be a lot better.  You might have to do slight
tweaking to get that to work right with gmail (like enabling your
account for "insecure" applications), but I believe it should work fine
with the stock nmh.

We have contribued work from Eric Gillespie to support the XOAUTH protocol
used by gmail; it's on my list of things to integrate, but it's kind of
complicated and I haven't yet had the time to figure it out.
