e-mail checking

[tdsmithj]

i am creating an improved e-mail script for a registration page for next year registrations. I found out that alot of people tend to insert an invalid e-mail address into the database.

i know there are regular expressions to check if the e-mail is valid but the issue is that people always end up with one character out e.g.

instead of james@uc3.co.uk,
some people put jame@uc3.co.uk

I was wondering is there a way to check if the e-mail is active before the reponse e-mail is send when the submit button is pressed?

i hope that makes some sense...

There is no foolproof way, due to the way mail servers work.

Make them enter the email twice, and make sure they match. Optionally, you can use some javascript to prevent them from just copy pasting what they typed into the first email field, to help ensure they actually type it out twice.
