Hi Michael,
I’ve renamed the rule, added the log function from the Remote Training and added a logmessage in filterServerJunkMailboxes(). When I didn’t see a logmessage this morning in the Console I sent myself a test message, and after 5 minutes I got a notification that there was mail. As the Junk mailbox did contain a few messages I saw them appear as well (just as the logmessage), so I think it is all okay now.
I figure the rules will be applied when there is actually a message in the Inbox. If there is nothing, no rule whatsoever will be evaluated; if there are messages all rules will be evaluated.
Now that I know it is working I will periodically check on the server to see if my Inbox will be filled with messages over and over and over again, as that was the original problem.
Thanks so far, and I’ll keep you posted.
