Abstract:
1. A method for journaling of e-mail messages, comprising: receiving a copy of a first e-mail message sent from or received on a mail server, wherein the first e-mail message contains metadata and content data and wherein the metadata of the first e-mail message contains a message-ID stored as an independent field in the metadata of the first e-mail message distinct from a subject of the first e-mail message and e-mail addresses for the first e-mail message that specify senders and recipients of the first e-mail message, wherein the message-ID identifies the first e-mail message as a particular e-mail message; recording the copy of the first e-mail message by a relocation service running on a journal server remote from the mail server, wherein the relocation service performs a method of recording comprising: determining whether a second e-mail message having said message-ID in the metadata of said second e-mail message has already been recorded; if the second e-mail message having said message-ID has already been recorded in a database of e-mail messages, adding the metadata for the first e-mail message to a set of metadata linked to content data of the second e-mail message in the database but not recording any of the content data of the first e-mail message; if no second e-mail having said message-ID has been recorded:
