Question

When users create an account on my site I want to make server validation for emails to not accept every input.

I will send a confirmation, in a way to do a handshake validation.

I am looking for something simple, not the best, but not too simple that doesn’t validate anything. I don’t know where limitation must be, since any regular expression will not do the correct validation because is not possible to do it with regular expressions.

I’m trying to limit the sintax and visual complexity inherent to regular expressions, because in this case any will be correct.

What regexp can I use to do that?

Answer 1

^\S+@\S+$
