SMTP check code in PHP – Download

Is there an updated version of the email validate class? Or some documentation about how the author implemented it?

I have tried a few ways. Right now, passing an array holding the email addys to be tested, and another holding the ‘from email values’ in an array, and my result set is such that the first element and the last element have value (1 in both) and the rest is the list of email addresses as the key, but no value.

It is a great idea, and I really would like to use it.

TIA

Cheers!

Thanks for writing this. I’ve done this in a terminal for years but having the PHP front-end is very useful. I’ve found the Google public DNS service nameservers useful to use with this script too: http://code.google.com/speed/public-dns/

please explain how to implement check mail code

hi its good but how to know the smtp_server ipadresss can any one tell me with examples of placing
appreciate and thanks in advance…….

I tried the script and it works well on linux. However, I have some issues with making it work on Windows. Anything that I am missing? I added DNS.php to the Net folder inside PEAR folder. Please let me know if anyone has any idea about this issue.
