Systems and methods for aiding communication terminal users in the management of incoming call and/or message arrival notifications. In an embodiment, a method comprises receiving a notification associated with an invitation to establish a communication session between a communication originator and an intended recipient or to the availability, for retrieval and/or access, of a voice, text, or e-mail message. The notification is processed based on a passively derived classification or score assigned to the communication originator. A passively derived classification or score is one which does not depend upon the recipient of any prior communication to identify and/or characterize the originator of the prior communication. In some embodiments, delivery of a message and/or an invitation to communicate is automatically blocked or accepted based on the classification. In other embodiments, an enhanced notification is generated and forwarded to a communication terminal associated with the intended recipient.
