Email REGEX is too strict

Postby aarcro » Mon Oct 24, 2011 1:53 pm

The regular expression you are using to validate email on the registration page is to strict. It doesn't allow subdomains in the destination part: me@my.server.com should validate.

It also didn't allow my @utulsa.edu domain. Presumably because it has a '-' in the local part.

Where are you seeing this exactly and what is the error shown?

From what I see, the only checks on email address for the contest registration are:

That one has been entered (i.e. the length is > 0)
That it's not a duplicate of one already registered.
That a lookup on the string following the last @ sign has a valid MX record. (if it doesn't there isn't any place to send the email to anyway)

Subdomains or out of the ordinary characters shouldn't be able to effect this at all.

Hmm, I don't know then. It was during registration for the contest submission account. It said that the e-mail address didn't exist.
