How are you hoping to do this? The regex to validate an email
address syntactically is pretty large:
http://ex-parrot.com/~pdw/Mail-RFC822-Address.html
And no, I'm not kidding. If your regex is smaller than that, you aren't
validating email... you're validating something kinda like email.
Just in my opinion, this regex is completely too large. For basic
validating something like:
^[A-Za-z0-9!#$%'*+-\/=?^_`{|}~][A-Za-z0-9!#$%'*+-\/=?^_`{|}~\.]{0,6...@[a-za-z0-9-]+(\.[a-zA-Z0-9-]{1,})*\.([a-zA-Z]{2,4}){1}$
works very well
not good: eg:
fails this valid address* : ad...@xxx.museum
accepts this invalid one : y...@gmail..com
musedoma replaced with several x to protect the innocent from spam
in some contexts email adrresses with no domain part are valid
addresses with [bracketed] mx servers instead of a domain and/or bang
paths are also allowed (but not in common use and often not desirable)

not good: eg:

yes it does, but all I need to change is {2,4}, to {2,6} or {2,}
accepts this invalid one : y...@gmail..com
and not it does not. I just tested it here.
The regex helps to avoid stuff like this:
f...@bar.com
foo@@bar.com
f...@.bar.com
f...@bar
etc

Fails on .mobile TLD. Has a pointless {1} in it, which does
absolutely nothing, providing that the creator of the regex was already
missing a few clues.
That's the problem with these kinds of regex... you test it on what
you know, but you're not consulting the *actual* *internet* specifications
(which have been readily available since the dawn of Internet time).
Either use the regex I pointed to already, or stay with the simpler:
/\...@.*\s/
which will at least not deny anyone with a *perfectly legitimate* email
address from making it into your system.
Or, use your regex *only* in an *advice* category, with the ability
for the user to say yes, I'm really sure this is my address.
Please, for the sake of the net, do the Right Thing here. This is
what I'm arguing for. Anything less than that, and your code deserves
to end up in thedailywtf.com as an example of what *not* to do.
