Try to search on google about regular expressions.

Do you want to test if an email is of a valid construction or check whether the address is a genuine email address?
A preg_match expression can check for most address formats, but you will find different regular expressions making this claim.
The only way to truly test if an email address is genuine is to obtain a reply from that address, unless you have access to the email providers directory.

if you are using smtp to send ur mails then you can check wether the email exist or not , simply send a mail to the address and set bounce mail address if the mail bounced it will be notified on your given bounced mail address you can then check it

Hi all,

not wanting to be pedantic but it is common practice to configure email servers not to respond to incorrectly address emails - this is done to stop directory harvesting attacks.

Another approach implemented is tar pitting where a non delivery response is sent after a delay, again to reduce the effectiveness of directory harvesting attacks.
