OmniTouch ACS deployments may have multiple IM application servers with their own
unique Node IDs, each maintaining IM logs for users associated with that application
server. A user cannot own an IM session.
Note: Calls for each IM session are identified using a session ID and stored in
/var/log/sessionlogs.
All IM message exchanges are stored in /var/log/thslog.
The following are the basic features and operating parameters of SMTP IM archiving:
• Archives messages in batches. Batch processing runs approximately every 15 minutes
(default).
• Archives only new IM content since the last batch process was run.
• Sends a separate SMTP message for each IM session that has new IM content since the
previous send cycle.
• Stamps each SMTP message in the message Subject with a unique, monotonic
sequence number.
• Retains each SMTP message in the ACS server for 30 days (default). The default may
be overridden.
• Deletes expired SMTP messages automatically from the OmniTouch ACS server.
• Provides a URL interface to retrieve previously sent archive messages using the
sequence number as key to fetching a particular SMTP message.
The SMTP message structure
Each SMTP message contains one or more IM messages that have been sent as part of a
single IM session. The basic structure of the SMTP message is a standard header, followed
by a multipart message body composed of individual IM messages in plain text. The
following is an example as received by a test archiving service. Notable headers are
highlighted.
