HTML form - check if email entered correctly?

Question

I creating Contact us form and i want in email section that if email entered wrong way (not name@example.com), user wouldn't be able to submit form.

input:

<input name="email" type="text" value="" size="30"/>

eMail validation is fraught with difficulties. The only way to be sure an email address is valid is to send an email to it and track a response. — , Dec 13 '13 at 21:16
@zeeba `email` is an HTML5 type, and it's not supported very well even in current browsers. — , Dec 13 '13 at 21:17
Just Google "email validation form", there are a LOT of articles on this. — John, Dec 16 '13 at 13:50

With regexp using javascript/php (or whatever) you would be able to validate an email format : presence of "@", presence of ".dom", but you will have to hard code to avoid something like "example.com".

I would suggest to use a validation/activation mechanism : send an email with a link, when user click the link you receive a notification, that means that email is valid so you can take care of it !

You can check this topic : Validate email address in JavaScript? But it does not take care about something like "name@example.com". As Mike W said in comments, the only way to validate a valid email is to send an email.

Also, you could have fun trying to trap auto-response for invalid email by checking the sender mailbox ;)
