Are you validating fields entered in a web page ?  In that case it's
probably relatively (hah!) easy as you can assume it's already in
mailbox format (e.g. a at b instead of "Foo!Bar" <a at b> or a at b (Foo!Bar)),
and don't have to handle most of the encoding, escaping and embedded
comment handling that the RFCs go into great lengths about.  Also things
like mail groups that can crop up in headers are not likely to appear.
