For this issue, Depending on what you are trying to do, you might be able to use the built-in mail rules or something like that. But there are two problems: Your organization might not allow use of rules, and rules might not do what you want. For example, rules cannot forward mail to another address. The most flexible approach, as always, is to write a LotusScript agent to do your bidding.
First, decide what type of agent to run. For example, in Lotus Notes you can choose to run a “before mail arrives” or “after new mail has arrived” agent.
Agent details aside, and not knowing exactly what you are trying to do, you most likely need to use the NotesDatabase.UnprocessedSearch method. Search and UnprocessedSearch are fabulously useful methods that let you select documents exactly the way you build a view: by using a selection formula.
