How to use

1. First of all, you need to clone this repository using git clone https://github.com/harrisonratcliffe/php-smtp-checker.
2. Now browse to the PHP script on your browser and fill out the form with your SMTP settings.

Note: for the 'Debug Mode' value, use the below levels to determine which one is best for you.

SMTP::DEBUG_OFF (0): Disable debugging (you can also leave this out completely, 0 is the default).
SMTP::DEBUG_CLIENT (1): Output messages sent by the client.
SMTP::DEBUG_SERVER (2): as 1, plus responses received from the server (this is the most useful setting).
SMTP::DEBUG_CONNECTION (3): as 2, plus more information about the initial connection - this level can help diagnose STARTTLS failures.
SMTP::DEBUG_LOWLEVEL (4): as 3, plus even lower-level information, very verbose, don't use for debugging SMTP, only low-level problems.
