5.4 Client Access Controls

Messaging Server includes access-control features that allow you to determine which clients can gain access to its POP, IMAP, or HTTP messaging services (and SMTP as well). You can create flexible access filters that allow or deny access to clients based on a variety of criteria.

Client access control is an important security feature of Messaging Server. For information on creating client access-control filters and examples of their use, see 23.7 Configuring Client Access to POP, IMAP, and HTTP Services and 23.9 Configuring Client Access to SMTP Services.
