如何记录SMTP身份验证事件？
入站SMTP身份验证
在思科邮件安全设备(ESA)上，在入站连接期间（为了获得中继访问权限）进行的身份验证尝试在成功和不成功时记录在mail_logs中。所有相关条目将与所涉ICID相关联。
成功：
Wed Apr 22 11:43:59 2009 Info: New SMTP ICID 450 interface IncomingMail (172.16.155.16)
address 172.16.155.102 reverse dns host unknown verified no

using AUTH mechanism: PLAIN with profile: IncomingAuthentication
Wed Apr 22 11:47:56 2009 Info: ICID 451 close
出站SMTP身份验证
从ESA中，当传送到特定主机（通过“传出”SMTP身份验证配置文件和引用该配置文件的SMTP路由配置）需要SMTP身份验证时，成功的和不成功的身份验证尝试都会记录到mail_logs中。所有条目将与所讨论的DCID相关联。
成功：
