New administration program:
You configure and manage mail services using Mac OS Server Admin. You can use Mac OS Server Admin on the server or any client computer on which you've installed the administration software.

Protocol transcripts:
You can set up the mail server file to record transcripts of sessions for each protocol. You can use this feature to troubleshoot problems. (Protocol transcripts log a large amount of information. To avoid creating very large files, you usually turn on this feature long enough to solve a problem.)
