withdrawing mails

There may have  no way to withdraw it once it arrives
/usr/spool/mail/name/xxx in current UNIX implementation.

How about  a modification in BSD4.x such that the files in 
/usr/spool/mail/receiver can also be writable by sender.

By doing this, it may not be too late before it is readed.

This is the point that US mail beat E-mail:

One can alway withdraw a mail from one's own mailbox before
mailman comes. This is usually one  night and one  morning
( may be one long weekend ).
