Messages exchanged among users of a relationship management and work collaboration system are organized within user-defined, secure communication channels organized according to user-defined hierarchies that represent the users' personal relationships with one another. Security of the communications channels is maintained using individual, dynamic keys, each of the keys being uniquely associated with a respective one of the channels, and being generated according to combinations of individual passwords established by each respective channel's participants. In-bound messages in the form of e-mails are received and associated with respective ones of the channels according to e-mail aliases associated with the inbound messages. Out-bound e-mails may be sent to channel participants according to e-mail addresses associated with the participants and channel preferences established by the system users. In some instances, messages are posted or not posted to those of the channels under the control of respective moderators and channel participants.
