本文描述如何查看邮件登录顺序确定从在思科电子邮件安全工具(ESA)或Cisco安全管理设备(SMA)的检疫发布的消息的处理。

当消息从检疫时发布,那在哪里被记录?

在ESA,当您发表从IronPort垃圾邮件检疫(ISQ),策略检疫,或者其他自定义检疫的一个消息,操作和相关的事件在IronPort文本邮件日志(mail_logs)文件报告。日志条目参加与原始MID。  

接近跟踪的最佳方法此发生故障被检疫原始消息的获得或者主题。其次,它的搜索在然后看到的日志看到是否从检疫发布,末端邮件服务器是否接受它或重新启动它。

示例,搜索邮件日志发送方“spam@test.com” :
 

> grep -i "spam@test.com" mail_logs
Wed Aug 13 12:59:36 2014 Info: MID 1357 ICID 10152 From: <spam@test.com>
Wed Aug 13 12:59:42 2014 Info: MID 1357 SPF: mailfrom identity spam@test.com None
Wed Aug 13 12:59:57 2014 Info: MID 1357 ready 185 bytes from <spam@test.com>

您将要注意消息ID (MID)和交付连接ID (DCID)。

我们能看到此特定MID发送对从全双工mail_logs的垃圾邮件检疫或者消息跟踪:

Wed Aug 13 13:00:08 2014 Info: Message finished MID 1357 done
Wed Aug 13 13:05:11 2014 Info: ICID 10152 close

一旦发布,下面是寻找什么的示例在从ISQ发布的消息:

Wed Aug 13 13:02:14 2014 Info: Start MID 1359 ICID 0 (ISQ Released Message)
Wed Aug 13 13:02:14 2014 Info: ISQ: Reinjected MID 1357 as MID 1359
Wed Aug 13 13:02:14 2014 Info: MID 1359 ICID 0 From: <spam@test.com>
Wed Aug 13 13:02:14 2014 Info: MID 1359 ICID 0 RID 0 To: <end_user@domain.com>
Wed Aug 13 13:02:14 2014 Info: MID 1359 Subject '[SPAM] This is spam?'
Wed Aug 13 13:02:14 2014 Info: MID 1359 ready 1445 bytes from <spam@test.com>
Wed Aug 13 13:02:14 2014 Info: MID 1359 queued for delivery
Wed Aug 13 13:02:14 2014 Info: New SMTP DCID 165 interface 192.168.0.199 address
192.168.0.200 port 25
Wed Aug 13 13:02:15 2014 Info: Delivery start DCID 165 MID 1359 to RID [0]
Wed Aug 13 13:02:15 2014 Info: Message done DCID 165 MID 1359 to RID [0]
Wed Aug 13 13:02:15 2014 Info: MID 1359 RID [0] Response '2.0.0 Ok: queued as
33B7380356'
Wed Aug 13 13:02:15 2014 Info: Message finished MID 1359 done
Wed Aug 13 13:02:20 2014 Info: DCID 165 close
 

在本例中,消息发布,并且接口(192.168.0.199)是ESA的监听程序,连接对(192.168.0.200)作为最终交付末端邮件服务器。

当您查看垃圾邮件检疫日志(euq_logs),版本操作显示以下:

Wed Aug 13 13:02:14 2014 Info: ISQ: Releasing MID [1357] for all
Wed Aug 13 13:02:14 2014 Info: ISQ: Delivering released MID 1357 (skipping
work queue)
Wed Aug 13 13:02:14 2014 Info: ISQ: Corpus status: 0
Wed Aug 13 13:02:15 2014 Info: ISQ: Released MID 1357 to end_user@domain.com
Wed Aug 13 13:02:15 2014 Info: ISQ: Deleting MID [1357] for all
Wed Aug 13 13:02:15 2014 Info: ISQ: Deleted MID 1357 for all
Wed Aug 13 13:02:15 2014 Info: ISQ: Cleared 8192 bytes (MIDs 1, for all
recipients) from database. Current bytes=0.

同样地,如果原始消息检疫对策略检疫,然后发布,您会看到类似于此示例:

Wed Aug 13 13:09:27 2014 Info: MID 1361 released from quarantine "Policy" (manual)
t=29
Wed Aug 13 13:09:27 2014 Info: MID 1361 released from all quarantines
Wed Aug 13 13:09:27 2014 Info: MID 1361 matched all recipients for per-recipient
policy DEFAULT in the inbound table
Wed Aug 13 13:09:27 2014 Info: MID 1361 interim AV verdict using Sophos CLEAN
Wed Aug 13 13:09:27 2014 Info: MID 1361 antivirus negative
Wed Aug 13 13:09:27 2014 Info: MID 1361 queued for delivery
Wed Aug 13 13:09:27 2014 Info: New SMTP DCID 169 interface 192.168.0.199 address

Wed Aug 13 13:09:27 2014 Info: Delivery start DCID 169 MID 1361 to RID [0]
Wed Aug 13 13:09:27 2014 Info: Message done DCID 169 MID 1361 to RID [0]
Wed Aug 13 13:09:27 2014 Info: MID 1361 RID [0] Response '2.0.0 Ok: queued
as C702980356'
Wed Aug 13 13:09:27 2014 Info: Message finished MID 1361 done
Wed Aug 13 13:09:32 2014 Info: DCID 169 close

从策略检疫,消息从策略检疫发布,并且接口(192.168.0.199)是ESA的监听程序,连接对(192.168.0.200)作为最终交付末端邮件服务器。
