I see, that way loops are avoided. But sometimes, the envelope address is invented, as is my case (I don't have a permanent IP number).
The envelope (sender) from must be valid or everything breaks. You lose bounces, mailinglists won't work, and a lot sites won't even accept your mail anymore.
tiscali.es seems real enough.
Yes, but that's my header "from". I think my envelope would be
"cer@localhost" or "cer@nimrodel.valinor", which is my machine name.
Unless postfix is clever enough to change the "envelope sender" to match
the "header from" for all the differents addresses I use :-?
I don't think I can easily check that; but an email sent to myself has
this on the header:
Received: from nimrodel.valinor (193.152.137.137) by netmail.tiscalinet.es
(6.7.014)
id 3DF904860059AD7D for robin1.listas@tiscali.es; Mon,

Received: from localhost (localhost [127.0.0.1])
by nimrodel.valinor (Postfix) with ESMTP id 8E6B029B00

What would happened then? That could be the reasoning behind bouncing to the originator.
The originator is the envelope (sender) from, not the header from.
I'll have to read the howto again :-) -- Cheers, Carlos Robinson
