Note that that's a tiny bit loose; all components after an @ sign are
part of a domain name (except, occasionally, the first one, which might
be a machine name), and domain names are limited to [A-Z0-9-].

Since you're only trying to *spot* email addresses, and not validate
them, this is probably not a problem.

A slightly more important problem is that the LHS of the address can
also contain a "+" sign, and these are not uncommon in email addresses
these days, especially since gmail explicitly supports them.  It's
possible, though not common, that you could find a "%" sign as well.

So the full version of that would probably be

// Typed but not tested
lhs: name [ plushack | pcthack ]
rhs: [ machinedot ] { domaindot } tld
name: {{A}|{N}|{"&"}|{"-"}|{"_"}|[!" "!]}
plushack: "+" name
pcthack: "%" name
machinedot: {{A}|{N}|{"-"}|{"_"}|[!" "!]} "."
domaindot: {{A}|{N}|{"-"}|[!" "!]} "."
tld: A A [{A}]
email: lhs "@" rhs
//

Remember .aero, .name, and .museum, among others.

Did I get all the punctuation right in there, Ken?  Been a while since
I had to write an edit stack from scratch.
