E-mail system which organizes e-mails into queues based on their locations and characterizes the e-mails. Metadata, indicative of the e-mail, is appended to the e-mail. The queues are organized based on the metadata, and processed. The metadata is always stored in local storage; and the message body may be stored in local storage, or in remote storage, depending on how long it will be until the message is sent. A special server manages whether the information is stored in local or remote storage.
