在之前给大家分享了一篇MDaemon日志查看方法—外发邮件，这次给大家讲述的是MDaemon日志查看方法–内接邮件。
“内接邮件（入站）”日志查看步骤
邮件内接（别人发给你）的过程，日志的经过步骤是：
SMTP-(in)—AntiVirus(反病毒检测)—AntiSpam（反垃圾检测）—Content-Filter（内容过滤器检测）—Routing（路由）
但一般查看SMTP-(in)即可，详细步骤如下：
（1）在别人发送邮件给您没有收到的情况下。请收集“发件人地址”、“收件人地址”和“发送时间”。
（2）进入MDaemon/Logs目录下。
（3）打开当天的smtp（in）日志，并按快捷键“Ctrl+F”或“编辑—查找”。输入收件人或发件人进行查找（对照时间）。
（4）以下是smtp（in）日志的具体分析
