======LogDB.Sessions table======
The [[LogDB]].Sessions table contains a record of all 'sessions' logged by VPOP3. A session is something like a POP3 server session as an email client downloads messages, or an SMTP client session as VPOP3 sends a message out to the Internet, and so on.

=====Columns=====
  * sessid - this is a [[http://www.postgresql.org/docs/9.0/static/datatype-numeric.html|bigint]] sequential value which identifies the session uniquely in the database
  * datetime - this is the date/time when the session started (in UTC)
  * duration - this is the duration of the session (in seconds)
  * sesstype - this is a single character code indicating what type of session this is (see below)
  * errorcode - this is text containing any error detail about the session (eg invalid password etc)
  * name - this is text describing the session. This may contain client IP address, username etc

====Sesstype codes====
  * C = SMTP client (via relay)
  * F = SMTP client (LAN forwarding)
  * L = SMTP server (internal)
  * M = SMTP client (MX direct)
  * O = POP3 server
