Yes it is. The *only* correct regexps I am aware of for e-mail
addresses are on the order of a page in length. All shorter regexps
reject some valid e-mail addresses.
Just check for the . and @, and trust the user for the rest.

That regexp is just a simple example. It isn't even close to covering
all valid e-mail addresses. Don't use it.
