Things are  not that simple.  The official,  correct place to  send error
messages  is the  SMTP MAIL  FROM: field,  which is  [log in to unmask]
There are indeed  mailers and gateways that do not  respect this and send
the message  elsewhere. Some look  at the  "Sender:" field, some  look at
"From:", and  some look at "Reply-To:"  (this is in fact  the most common
case).  The  gateway you  were  having  problems  with clearly  looks  at
"Sender:".

It looks at  both "From:" and "Sender:",  if that is what  you meant. But
not at the subject field.

No, not for now. I'll keep it in mind.
