This is related to bug 1190906 whose code was *poorly* 
written by me (ie. the fix assumed a dict result whereas 
the mailer code stringifies it) 
 
A quick hack fix would be to look for "unknown user 
account" in the error string. 
 
I suspect a better fix would be to squash and ignore any 
smtplib.SMTPException raised during the bounce_message 
call in mailer. 
 
What do you think?

as far as i understand, this is mostly a spam case (user is
not authorized to mail the tracker and cannot be mailed
back). so yes, i think it is ok to log and ignore all smtp
errors here.

Going with the squash option, with a note in the code to 
maybe do something better in the future.
