Figure: SMTP architecture illustrates the components of Enterprise Vault SMTP archiving.
SMTP message archiving involves three basic steps:
You must set up a mechanism to send the SMTP messages for archiving to a Microsoft SMTP Server. The Microsoft SMTP Server must not be configured as a relay, so if necessary you should send copies to it. For example, in Figure: SMTP architecture a third-party SMTP messaging server receives SMTP messages and relays them on to their destinations. For specific message recipient domains, the SMTP server also sends a blind copy (BCC) to the Microsoft SMTP Server for Enterprise Vault SMTP archiving to process.
SMTP archiving processes the messages that the Microsoft SMTP Server receives, and stores them as EML files in a holding area.
You must set up the holding area with a domain root folder for each recipient address domain. You can configure SMTP archiving to create a mailbox folder with an archive point automatically for each recipient address; otherwise you must create the mailbox folders and archive points manually.
SMTP archiving stores the messages in the holding area in a subfolder structure as follows:
DomainRoot\MailboxName\Year\Month\Day\Hour
symantecdomain\j.doe\2009\08\30\09
Enterprise Vault's File System Archiving (FSA) takes the EML files from the holding area and stores them in archives. FSA creates the archives based on the location of the archive points in the holding area folder structure. If SMTP archiving created the archive points automatically, FSA creates a separate archive for each mailbox.
