12-proxy-smtps.php

<?php

// A simple example which uses a secure SMTP connection to Googlemail through a HTTP CONNECT proxy.
// Proxy can be given as first argument and defaults to localhost:8080 otherwise.
// This example highlights how changing from plain connections (see previous
// example) to using a secure connection actually adds very little complexity
// and does not mess with your actual network protocol otherwise.
// Please note that MANY public proxies do not allow SMTP connections, YMMV.
