I wonder how many of you have sent a mail message then wished you hadn't?  I
would like to see a facility for cancelling messages, similar to the way it is
done by the usenet software:

From: Stephen J. Muir <stephen@comp.lancs.ac.uk>
To: Steve Kille <steve@cs.ucl.ac.uk>
Subject: Re: an idea
Control: cancel <861122065645.4523@dcl-csvax.comp.lancs.ac.uk>

Please ignore the above message.

If the target site had software to recognise the "Control" header, it could
remove the original mail message from the user's mailbox (if it was still
there), or from its mail queue if it had not been delivered, or from it's UUCP
(or whatever) queue if it was being relayed, or whatever.

Does anydody else like this idea?
