Out of curiosity, I tried this.  I wrote a message with following headers:

    From: philip@siberia.demon.co.uk (Philip McNab)
    To: hamster@non.existent.site.anywhere
    Cc: whale@non.existent.site.anywhere
    Subject: Re: KA9Q .WRK files - Reverse path
    ...

And hacked the .wrk file to read as follows:

     post.demon.co.uk
     errors@siberia.demon.co.uk
     hamster@non.existent.site.anywhere
     whale@non.existent.site.anywhere

When the messages bounced, they were returned to errors@siberia.

Unfortunately, I forgot to send a copy to myself, so I don't
know what happens on a correctly delivered message: I fear that
the headers would start with the line

    From errors@siberia ....

In any case, I suspect that all this is in flagrant breach of some
RFC ...
