smtp發送郵箱個人覺得比php mail函數要實用的多了，mail函數不是隨便可以發郵箱的需要進行相關配置哦，下面我們來看一個關于smtp類發送郵箱與問題解決方法。

當你還在糾結php內置的mail()函數不能發送郵件時，那么你現在很幸運，此時的這篇文章可以幫助到你！

php利用smtp類來發郵件真是屢試不爽，我用過很久了，基本上沒出過問題。本博客后臺，當博主回復留言時候，會自動給網友發一封有新回復提示的郵件也是用的本文這個方法實現的。

smtp類發送郵件的方法其實很簡單，也很穩定，類是別人已經寫好的了，你只需要調用就行了。幾行簡單的配置就能發郵件，是不是很期待的試一試呢！

email.class.php文件,代碼如下:

<?php

$mailtitle = $_POST['title'];//郵件主題
