As far as the server is concerned what are the differences? As far as I can tell both types of code are exectued by the router, rather than AMGR.
Do they have the same impact on CPU. If all my users created a rule to auto file a message to a folder based on the subject, is that any different to me creating a before mail arrives agent to do the same thing?
Is there somewhere I can try to predict what the impact would be on adding a standard auto filing before mail arrives agent to about 850 mail files on one server?
Thanks,
Simon
