Always bounce to the envelope address. If it's an autoresponse, it's best to use a null sender from as well.
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.
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.
Well, my Spanish isn't really good enough to write those so I'm kind of dependent on volunteers (hint ;)).
Hint taken, I'll have a try - but I'm not fast at that :-)
