用phpmail发送邮件，简单实现php发邮件功能！

摘要：发件人是我的邮箱收件人是我的邮箱当我点击发送的时候，我就会在我的邮箱的已发送列表看到一篇发送的邮件然后登陆邮箱就可以看到收件箱有一封刚刚发过来的邮件。

很多网站都开始有邮箱验证码验证了。
例如网站评论有人回复了，你就能立马收到邮件。
这些功能是如何实现的呢？
其实就是用php实现的，当然这样的类很多，我这里给大家分享的是phpmail

首先该文件有一个封装类和一个配置

很简单，然后一个表单进行发邮件。

发件人是我的163邮箱
收件人是我的QQ邮箱

当我点击发送的时候，我就会在我的163邮箱的“已发送”列表看到一篇发送的邮件

然后登陆QQ邮箱就可以看到收件箱有一封刚刚发过来的邮件。
如果收件箱看不到，请到垃圾箱找找......我的是在垃圾箱找到的。

这就是整个发送过程！

注意：$smtppass这里不是填邮箱的密码，填密码是不行的，要在163后台设置打开授权开关设置一个授权码，打开所有的服务即可。

一般发件人和收件人都在同一个网域就不会被拉入黑名单！发件人用腾讯的，收件人也用腾讯的，那就绝对没问题。

邮件发送那点事

摘要：配置在中，修改为，这样的函数就可以发出正常的邮件了。没找到哪儿改，所以我就直接用发送了。同时，邮件发送是一个耗时操作，不应该让进程长时间等待。相对复杂一些，它会对邮件内容进行签名，然后收件服务器通过获取公钥，核对签名是否正确。搭建Postfix 操作系统我个人比较喜欢CentOs,原生的系统都装有，没有的话可以自己谷歌，这个很简单，跳过。需要注意的是，Postfix默认只对本地I...
