Quoted from RFC822:

 :      4.4.4.  AUTOMATIC USE OF FROM / SENDER / REPLY-TO
 : 
 :         For systems which automatically  generate  address  lists  for
 :         replies to messages, the following recommendations are made:
 : 
 :             o   The "Sender" field mailbox should be sent  notices  of
 :                 any  problems in transport or delivery of the original
 :                 messages.  If there is no  "Sender"  field,  then  the
 :                 "From" field mailbox should be used.
