Allows two letters domains please use of email =~ /(.+)@(.+)\.(.{2})/ instead of
email =~ /(.+)@(.+)\.(.{3})/ for three letters domains.

Thanks !

As usual, every SINGLE email regex matcher here has FAILED to read RFC822. As with all the other versions, THIS REGEX IS WRONG. DO NOT USE THIS REGEX. DO NOT. AND PLEASE STOP POSTING BROKEN REGEX TO MATCH EMAIL HERE. {sigh}

%r{^(?:[_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-zA-Z0-9\-\.]+)*(\.[a-z]{2,4})$}i

this is the most appropriate one… with all the validations including the domain extensions…

This should allow for two letter domains, to take domains like .tv and .sc into account.

‘ test@ test .com’ =~ /(.+)@(.+)\.(.{3})/
Note the spaces.

/(\A(\s*)\Z)|(\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z)/i
This one is more exact but is still not one that follows RFC.
