A domain (101) has a primary e-mail server (103) with an e-mail delivery
address (109), and at least one backup e-mail server (105) with an e-mail
delivery address (111). A trap manager (115) adds at least one trap
e-mail delivery address (113) to an e-mail delivery address list (107)
associated with the domain (101), the trap e-mail delivery address (113)
resembling a backup e-mail server delivery address (111) and pointing to
the trap manager (115). The trap manager (115) receives (201) e-mail sent
to the trap address (113), and determines whether received e-mail
comprises spam (119).
