 So the question is what the SMTP code should use as fallback (the sendmail
 code
 seems to omit the '-f addr' part in that case)...

 Use username (or 'nobody' if user can't be determined) as mailbox and
 hostname
 (or 'localhost' if hostname can't be determined) as domain part?

 Since the sendmail-calling code explicetely tests for 'from' being exactly
 one address,
 I guess it's an invalid assumption that a message always has a sender
 address? Though
 I'd be interested as to when this happens (and why) since mutt should IMHO
 always generate
 some sender for any outgoing message...
