Vivek is right.  Here's the relevant references :

RFC 2822, sections 3.6.5, 2.2.1
RFC 2822, sections 3.4, 3.2.4, 3.2.5

RFC 2047   <-- this one shows how to put non-english text in headers


Recent postifx snapshots have an option strict_7bit_headers (or
something like that) to reject all such invalid email.

I have now posted some exim ACL entries from Greg Ward at
http://dman.ddts.net/~dman/software/exim/ to do the same thing onthe
Subject: and From: headers.
