mtaReceivedVolume

The total volume of messages received since MTA
initialization, measured in kilo-octets.  This volume should
include all transferred data that is logically above the mail
transport protocol level.  For example, an SMTP-based MTA
should use the number of kilo-octets in the message header
and body, while an X.400-based MTA should use the number of
kilo-octets of P2 data.  This includes messages transmitted
to this MTA from other MTAs as well as messages that have
been submitted to the MTA directly by end-users or
applications.
