bounced back email?

[vbbit]

Hello, is there a way to tell if the email that I used from my page send to the user correctly? I mean is there a way we can tell if the user's email is invalid email so that when I send info to them using PHP mail, I will get something bounced back to my email or display on the webpage?

Nope. That's the SMTP server's job.

There is a way to verify if an email address exists (that does not guarantee delivery/bounce), but it involves sending a socket stream. I don't know if PHP has socket streams, so someone can step in here.

what you mean to verify if an email address exists?

With sendmail you can redirect certain emails through a program, so if you fix your reply-to address to a send mail installation, you can send all emails to the PHP script including delivery failures.

I am not quite understanding visualaid, what do you mean? and how can I accomplish that?

when you send an e-mail, you will get a bounce. Configure your app to check the e-mail on the server of the address it will bounce back to. However, there might be some server configuration do handle that since you are sending the mail from a php script.

anyway, after you check the e-mail, parse it and determine if it is a bounce.
