Email validation

Yes, by judging that preg match, after @ sign it expects minimum of 1 letter / number.

I am using following script for domain and e-mail checks:

You have domains / email and phones scripts there.
Simply add them as a helper, load it and call function (providing e-mail address).

It uses IANA list of domains to check validity of extension and it can even 'call' the mail server to check that e-mail address really exists on that server - which makes it almost 100% safe check for the mail.

Cheers,
