不从服务器删除电子邮件时PHP发送到mysql数据库的问题

http://www.phpclasses.org/package/3324-PHP-Retrieve-e-mail-messages-into-a-MySQL-database.html

它检查电子邮件帐户并将消息下载到mysql数据库中.它工作正常,但是在每个循环结束时(为收件箱中的每条消息循环),它会删除电子邮件.我知道如何阻止它删除电子邮件,但问题是由于某种原因,脚本不会将任何新电子邮件插入数据库,除非我允许它删除邮件或收件箱完全为空.

这是上面引用的php类的结尾部分.此部分只循环遍历每条消息并将其插入数据库中,如果设置它将删除消息.总结我的问题是让脚本正常工作而不需要删除邮件或有一个空的收件箱.
