Abstract
Abstract Firewall host systems (26), (28) and (30) interface between private networks (14), (16), (18) and a public network (12). The firewall host systems (26), (28) and (30) manage alias databases (21), (25) and (29). The firewall host system (26) communicates updates to its alias database (21) to the firewall host system (28) which redistributes the updates the fireball host system (30). The firewall host system (30) then reinitializes its alias database (29) using the information received from the firewall host system (26) through the firewall host system (28). In addition, each of the firewall host systems (26), (28) and (30) provide a graphical user interface (66) which allows for the proactive maintenance of mail message queues through the provision of a mail message queue display area (68) and a command area (70) and a search area (74).

Claim 3
Dependent Claim
29 words
The management system of claim 1, wherein the second peripheral host system is operable to authenticate the re-sent electronic mail message that it receives in order to ensure security.
Claim 4
Independent Claim
70 words
A method for managing electronic mail comprising: (a) maintaining a distribution list of a first peripheral host and at least one second peripheral host at a central distribution host; (b) receiving an electronic mail message containing alias change information from the first peripheral host at the central distribution host; and (c) communicating the electronic mail message to the at least one second peripheral host in accordance with the distribution list.
Claim 5
Independent Claim
70 words
A method for managing electronic mail comprising: (a) maintaining a distribution list of a first peripheral host and at least one second peripheral host at a central distribution host; (b) receiving an electronic mail message containing alias change information from the first peripheral host at the central distribution host; and (c) communicating the electronic mail message to the at least one second peripheral host in accordance with the distribution list.
