I've seen no references to RFC 2822 in this thread ... please note that what
all these regexes catch is unlikely to be exactly the set of all valid RFC
A quick look suggests (among other things) that addresses may start with '-'
or '_' and /lots/ of other characters, and the domain part does not (of
course) need to contain a '.'.
People get more than annoyed when some input form tells them that their
email address is invalid ...
