I am trying to keep a running record of the users that are accessing our OSX 10.6.8 Mail Server using POP instead of IMAP.
The Server Admin application features a running list of Mail connections under the "Connections" tab. This includes the user name, originating IP address, connection length, type (IMAP / POP) and overall connection count. However, the application doesn't seem to support logging these connections, and the mail.log only shows message transactions, not client logins (and there is no explicit option in the settings to track this data).
Is anyone familiar with a straightforward way to keep track of POP connections server-side? I'd like to build a list of those users so they can be migrated to IMAP, but so far short of visually monitoring the "Connections" window, there doesn't seem to be an obvious way to do so.
