My Spanish is not so bueno, but I agree with Jorge that you probably don't want to have strict constraints here.

This is especially true with email addresses because the [email address specification](http://emailregex.com/email-validation-summary/) is maddening. For me, the best way to validate an email is to send an email to that address with a link inside and see if someone clicks that link. The next best way, especially if you are offline, is to make sure there is no obvious typo.

So what I check is at least one non-whitespace character, followed by an `@`, followed by at least one non-whitespace character, followed by an `.`, and then at least one non-whitespace character. Something like this:  
`regex(., '\S+@\S+\.\S+')`

That should allow most common email addresses and typos like whitespaces and missing the @ and the period. Technically, this will reject valid email addresses (e.g., bob@local) but it's good enough.
