modx で sendmail 使わずに google apps に smtp する方法
/* SMTP variables を設定
http://forum.whmcs.com/showthread.php?t=13845
↑の設定のほぼパクリ。ただ、もとネタのように、 "tls://" を tls のトリガーに使ってしまうと、コロンのせいで explode されてしまう。(e.g. "smtp1.example.com:25;smtp2.example.com")のフォーマットに対応するため。。。
なので、 tls// のみをトリガーにする。後の strpos 部分と一致してれば、トリガーは何の文字列でもOK。
*/

// SMTP VARIABLES

var $Host = "tls//smtp.gmail.com"; // the "tls//" is used later to trigger tls
