唠叨几点：
1、这个类是国外的一个大神写的（receivemail.class.php），我拿来改了。核心部分我还改不来。
2、附件读取部分有问题，经测试，读取不到附件。
3、邮箱的每一份邮件，并没有一个唯一DI，读取邮件总数后递减for循环就可以开搞了。
5、邮件的读取很慢，尤其是 $server_type = 'imap'; 的时候，更慢。
6、邮件太多的情况下，php读取不能一次性读完，我的处理办法是，crontab去启动shell脚本，用shell脚本去启动php脚本。
php脚本每启动一次就统计总邮件数，for循环递减读取若干条邮件，读完就删除邮件，当邮件总数为 0 时返回 0 ，否则返回 0 。
shell脚本得到php脚本的返回值，判断是否要继续启动php脚本。当然我这个处理办法是根据我的公司业务需求来的。具体情况具体分析。
这样做也有个好处，因为php长时间读取邮件，那个邮件的连接资源极有可能会断掉。它不断掉，你连接数据库的资源也会断掉。
下面是shell的伪代码。
