用phpmail發送郵件，簡單實現php發郵件功能！

摘要：發件人是我的郵箱收件人是我的郵箱當我點擊發送的時候，我就會在我的郵箱的已發送列表看到一篇發送的郵件然后登陸郵箱就可以看到收件箱有一封剛剛發過來的郵件。

很多網站都開始有郵箱驗證碼驗證了。
例如網站評論有人回復了，你就能立馬收到郵件。
這些功能是如何實現的呢？
其實就是用php實現的，當然這樣的類很多，我這里給大家分享的是phpmail

首先該文件有一個封裝類和一個配置

很簡單，然后一個表單進行發郵件。

發件人是我的163郵箱
收件人是我的QQ郵箱

當我點擊發送的時候，我就會在我的163郵箱的“已發送”列表看到一篇發送的郵件

然后登陸QQ郵箱就可以看到收件箱有一封剛剛發過來的郵件。
如果收件箱看不到，請到垃圾箱找找......我的是在垃圾箱找到的。

這就是整個發送過程！

注意：$smtppass這里不是填郵箱的密碼，填密碼是不行的，要在163后臺設置打開授權開關設置一個授權碼，打開所有的服務即可。

一般發件人和收件人都在同一個網域就不會被拉入黑名單！發件人用騰訊的，收件人也用騰訊的，那就絕對沒問題。

郵件發送那點事

摘要：配置在中，修改為，這樣的函數就可以發出正常的郵件了。沒找到哪兒改，所以我就直接用發送了。同時，郵件發送是一個耗時操作，不應該讓進程長時間等待。相對復雜一些，它會對郵件內容進行簽名，然后收件服務器通過獲取公鑰，核對簽名是否正確。搭建Postfix 操作系統我個人比較喜歡CentOs,原生的系統都裝有，沒有的話可以自己谷歌，這個很簡單，跳過。需要注意的是，Postfix默認只對本地I...
