An e-mail system implemented on a server having a network connection receives and forwards e-mail messages based on subscriber-supplied criteria. When a message is received addressed to the subscriber, characteristics of the message, such as existence of and size of attachments, are compared to characteristics previously supplied by the subscriber. If a match is found, the subscriber is notified, such as by a page to a pager carried by the subscriber, of the message and the nature of the match. Facility is provided at the server for the subscriber to then call the server, log on, and provide instructions for forwarding the matched message. Forwarding may be to such as a hand-held device or a notebook computer operated by the subscriber, or to a mailbox or mailboxes on other servers, or any combination. A subscriber is then in control of points of delivery of incoming e-mail messages.
