	RFC 2821 is used for envelope addresses in the SMTP dialog, 2822 
is used for header addresses.  If MTAs want bizarre characters in the 
recipient addresses, they need to make sure that they get used only 
in the headers and not the envelope.  Where you run into problems is 
where an address in one format is inappropriately used in the other.
