Validate EMail with RegExp...

My understanding of regular expressions is rudimentary,
at best.

I have this RegExp to to a very simple validation of an
email-address, but it turns out that it refuses to
accept mail-addresses with hypens in them.

Van anybody please help me adjust it so it will accept
addresses like dag-sunde@test-domain.net too?

Here's what got:

function validateEmail(eMail) {
return /^(\w+\.)*(\w+)@(\w+\.)+([a-zA-Z]{2,4})$/.test(eMail);
}

TIA...

(But if anyone know the answer...)

return /^[\w.+-]+@[\w.+-]+\.[\w]{2,7}/.test(eMail);

see http://mindprod.com/jgloss/regex.html. have a look at what \w is
short for, and use that expansion slightly modified.

Thank you all!

I ended up with thisone (wraps):

function validateEmail(eMail) {
return
/^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$/.test(eMail);
}
