Jason pointed me to http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html this site that has a perl module called Mail::RFC822::Address that will validate internet addresses. But take a look! Seriously!
To quote the site Implementing validation with regular expressions somewhat pushes the limits of what it is sensible to do with regular expressions Add to that the classic Jason quote: Visual Basic may make you stupid, but Perl apparently drives you insane Good stuff
