Please do accept my apology in advance, I do not mean or intend to
hijack an existing thread, but I have noticed something interesting in
the email you just sent to the list, so I have started a new thread... :)

Your sent email, came in marked as SPAM, and I wondered why...

yes, it is from Google, who sends a lot of spam, scams etc. but that
alone should not get it marked as spam... So, I looked and it is so
interesting... (maybe I need a life :) )

Dave, in the headers you literally have three email addresses:
Relayed For: <davec-b at rogers.com> - No SPF / Anti Forgery
Cc:<davecb.42 at gmail.com> - Which is currently a ->  ~all
Reply-To: davecb at spamcop.net and your SpamCop receive only addy, 
also a -> ~all

Which is why your relay is scored additional, as this is also what
spammers do very frequently (They use (rather abuse) @gmail with a reply
to of @outlook.com, etc) 

It is also interesting, that Google, probably in the interests of
becoming a better netizen?, has again started including relay headers,
again, after not including same for a long while...

Anyway, long winded, but here is the question: Do you not find many
fake sent from and backscatter issues to your @rogers.com? If yes, why
even still use it in your Thunderbird config?
