How to read email as they go out or come in in exchange

Question

I am trying to create a service where i can read email (based on subject) as they go out or comes in and save the email back to Database.

I can read from a mail box but i need something like everytime a email comes in check the subject and then do something.

How can i do that?

Thanks in advance.
