Yes, i'm connected from a xDSL from my Home.
My Thunderbird connects to the mail server (in USA, with static IP, clean as water and reverse dns).
The mail originates from my home; but the sender is the server... could be that? I tryed with others servers and it arrived ok.
I finded that the problem could be the "Message-ID" header...
in the postfix page I found this "http://www.postfix.org/BACKSCATTER_README.html"
where it's explained that the Message-ID shoud be "host.domain";
in my case, should be "...@mx.excelsior.stonetree.com.uy",
how is configured the Message id? Or how can this beheavor be changed.
Thanks a lot
