After some searching in RFC2822 it seems to me that the coma character in
address fields is used as address separator. see sections 3.6.2 and 3.6.3
(originator and destination fields) plus 3.4 (address specification).
The ',' may appear in address, if it's in quoted string.

exchange uses to separate users with ; because it uses , as separator in
fullnames. Yes, it sucks. However looking at mails from our exchange (2000)
server, all comas in From: are in quoted strings.
