Sending mail - Get a Complete Control

[eluser]smilie[/eluser]
Well, only thing I can think of is to use some class which will:

1) find out MX record for each e-mail address;
2) establish connection to the mail server from MX record;
3) send couple of commands, starting an e-mail.

In case e-mail address is not recognized by the mail server, you will know that that e-mail will bounce.

You can also use this class:

download from: http://code.google.com/p/blogchuck/sourc...emails.php

as it says in Wiki, second param to the class (TRUE) will also do the SMTP validation as explained above.

Do note, that this will rather slow down your e-mail batch, so if needed set up higher PHP execution time.

Cheers,
