Which "who" is Keith supposed to tell you he is?  The sending system? The MAIL 
FROM
the system is sending for? The RFC822 From: field? Note that these are *often*
different.

Some people want to verify the sending system, to make sure it's an authorized
sender of mail.

Some poeple what to verify the MAIL FROM, to make sure that it's coming from the
correct place (this is *different* than the previous).

And so on.
