RE: [:graph:]

Yes, but even this is changing.  I just saw a mention of domain names that
end in ".kids" or ".family"   That breaks the two-three char alpha string.

no experience with [:graph:], but i can probably help out your re a bit
in another way...

due to internic standards, domains must be alphanumeric and may include
a dash or underscore...also, the last part of an email with either be a
two- or three-digit alpha string...therefore, after your @, your re
might be more useful like this:

[[:alnum:]\._-]+\\.[[:alpha:]]{2,3}$
