I'm slightly confused. Well ok, i'm always confused. But...

A few users have rules setup where any emails that they receive where they are only the CC recipient they send out an auto reply saying I only look at CC emails x amount of time, and puts the emails into a different folder.

But, the sender is only getting the email once each time until the user turns off and on the rule again. I thought that it was only "vacation rules" that worked once, and actual specific rules that have been created should continually send a reply each time it is actioned?
