Although this is an email address issue, it only happens with popcorn,
and so I suspect the popcorn appolication is doing something wrong. I
don't have problems with emails to others.

I'm running Beowulf and using mutt as mailer. The mail.guardedhost.com
is my mail server.

It seems popcorn is sending its message from root@???, but
this address not owned by user. The diagnostic code saeems to say that
the dng@??? recipient does not recognize root@???.
