Ahhh... the beloved bat book.

I dropped it on my foot one time and was in a cast for 7 weeks.

One point of technicality (because those are the only kinds of points I'm
able to make): all of these regex's are probably wrong.

The regex for email addresses that follows RFC (2)821 fills a page in
Appendix B of O'Reilly's wonderful "Mastering Regular Expressions" book...
and the text has been shrunk, so it's probably more like two standard pages
of text.

There's a code snippet at http://examples.oreilly.com/regex/readme.html
that will tell you if an email address is valid or not, but it's full of
some pretty nasty regexes... so much so that it's not a bad idea to buy the
book to understand them (which is pretty good, actually...)

"I don't like sendmail, because no matter how many times they fix it, they
always fix the *second* to last root compromise." -- me

Later,
