Enable Logging for SMTP, NNTP, and HTTP Protocols
By setting the configuration properties of the virtual server associated with each messaging transport protocol, you can protect your mail system in multiple ways. The Internet protocols (SMTP, HTTP, and NNTP) enable you to use logging to track the commands the virtual server receives from clients. For example, for each message you can view the client IP address, client domain name, date and time of the message, and number of bytes sent.
When logging is used with Windows 2000 event logs, the protocol log enables you to audit the use of the virtual server and identify problems.
