eMail Bounce Handler for Mac

From Maxprog:

Maxprog is proud to present its new product, eMail Bounce Handler, a bounce e-mail filtering and handling tool. Bounce e-mail (sometimes referred to as bounce mail) is electronic mail that is returned to the sender because it cannot be delivered for some reason. Unless otherwise arranged, bounce e-mail usually appears as a new note in your inbox. E-mail users can encounter bounce e-mail because an addressee has changed his or her address, because their mail box is full, because the note is misaddressed, or for some other reason.
