I tested it by sending an email to myself... and of course I have a Rule
to forward everything I receive to my Gmail account. And that could have
been what showed up,
Except, I did see a bcc notation on one of the actual emails.
I need to do a bit more testing.
It could be that Entourage effectively ignores custom headers if they
are one of the standard headers you can enter while authoring messages.
I was afraid of that when I asked about this, which is why I was careful
to mention I had not tried it myself. Normally, you would add BCC
addresses in the message window where you add TO and CC recipients. I
can definitely imagine a scenario where Microsoft engineers might not
have anticipated that users may want to specify BCC recipients in *both*
places.[/QUOTE]
It's weird. I edited the Account the way you suggested.
I sent an email to myself, and it arrived in my Entourage Inbox.
I opened it, and my regular address was in the To: field.
AND there was a bcc header addressed to my Gmail account.
So it absolutely looked like it had worked.
However, my Gmail never received it.
What it did receive was the Forward of the incoming email.
I also sent to another address, and Gmail didn't receive that either.
Hmmm.
