Any way to check if an email address is active?

Post by Jeefo »

Is there a website or a script I can use to check if an email address is active? It would be much easier than emailing a lot of people and see if I get it returned by "mailer demon" (or whatever) back to me. Any help is appreciated. Thanks.

there is no reliable way without actually sending an email.

Even then programs are capable of "bouncing" it so it seems as though it's invalid. But that is the best method.

I have seen programs that claim to scan any domain for all active e-mail addresses but I never did test it out and I believe it was made purely for spam so I'm not going to publish the URL.

Some mail servers let you check addresses with the SMTP VRFY command. But not many. Most just return yes for everything.
