I think it does... in a broader sense.. If you use a smarthost, then the
mail that they send for you is not rejected, as their "HELO [domain]" is
valid, it can be found on the DNS. whereas mine is not. is this right?

Yes, that I understand, but what I was trying to say is that I gather that
when visible_name is set to your ISP, i.e. win.bright.net, or in my case
es.co.nz , then you appear as if you are masquerading as your ISP. Am I
right saying that? (this is not using a smarthost)

okay, this I did not know. I guess I would have to try my ISP..
the MAIL FROM: line is your email address right? so if mine is
mickyb@es.co.nz , which it is, my ISP should send it out without a problem
right?
Another question, is visible_name the name used in the HELO [domain] line?
or is it used for more or less than that?
