debian-el sender headers?

[Matt Price <matt.price@utoronto.ca>]

hi,

just downloaded & tried out the debian-el package (for using emacs to
report bugs.  It's great but the mail I sent got sent back to me by
bugs.debian.org with this message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  submit@bugs.debian.org
    SMTP error from remote mailer after end of data:
    host spohr.debian.org [128.193.0.4]: 550 rejected:
    there is no valid sender in any header line (envelope sender is <matt@www.somehostame.org>)

do I have to set a preference in exim4 (4.34-2), or somewhere in
emacs?  

thanks as always!
matt
