/* ---------- "Use of % in addresses?" ---------- */

In our implementation of email (over DDN), we often see sites that use
addresses in the form  user%subsite@host.subdomain.domain.  The use of the
% notation has been variously described as being part of RFC 822, RFC 733,
or JNT.  I've read 822/733, and while they will accept that as part of the
user portion of an address, I don't see that they define anything about that.
Have not had a chance to get documentation on JNT, but suspect it will show
the same thing.  
Where does the % notation come from?
Please email.
