Test For Valid Email Addy

Recommended Posts

Is there a php function that can test to see if a given email addy is live. I do not mean to see if the format is valid. I mean to see if the email address is real, without sending an email. Sort of the way one can ping a server to see if it is up, can one "ping" an email address?

There's not a built-in function to do that, but I'm sure someone has written one. You would need to look up the records for the mail server, open a connection to it, and send it SMTP commands to check for the given account. There's some information about it here:http://www.webdigi.co.uk/blog/2009/how-to-...nding-an-email/
