[sylpheed:31022] E-mail Debugging

[Paul Dickson]

Could someone write (and send me) a quick patch for sylpheed that will
prefix to a just downloaded message something on the order:

  Received: from POP, by Sylpheed (Message NNN of MMM); DATE/TIME

I'm attempting to determine why I'm getting duplicate E-mail.  The
duplicate E-mails are identical, but downloaded on separate sylpheed
email downloads.  I'm hoping if I can determine where the problem lies.

This has been bugzilla'd as:
  https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=192151
but I'd like the patch to provide more data.

Thanks in advance for any help provided.
