5.  Changes made since RFC 2249

   This revision corrects a number of minor technical errors in the
   construction of the mail monitoring MIB in RFC 2249 [18]:

   (1) All DisplayStrings have been changed to SnmpAdminStrings,

   (2) the conformance groups for different versions of this MIB have
       been corrected,

   (3) the required mtaStatusCode entry has been added to
       MtaGroupErrorEntry (which does not affect the bits on the wire in
       any way), and

   (4) the recommendation that an empty string be returned if the last
       operation was successful has been removed from
       mtaGroupInboundRejectionReason and
       mtaGroupOutboundConnectFailureReason as it conflicts with the
       stated purpose of these variables.

6.  Acknowledgements

   This document is a work product of the Mail and Directory Management
   (MADMAN) Working Group of the IETF. It is based on an earlier MIB
   designed by S. Kille, T. Lenggenhager, D. Partain, and W. Yeong. The
   Electronic Mail Association's TSC committee was instrumental in
   providing feedback on and suggesting enhancements to RFC 1566 [19]
   that have led to the present document.

8.  Security Considerations

   There are no management objects defined in this MIB that have a MAX-
   ACCESS clause of read-write and/or read-create.  So, if this MIB is
   implemented correctly, then there is no risk that an intruder can
   alter or create any management objects of this MIB via direct SNMP
   SET operations.







Freed & Kille               Standards Track                    [Page 31]

RFC 2789                  Mail Monitoring MIB                 March 2000


   However, this MIB does provide passive information about the
   existence, type, and configuration of applications on a given host
   that could potentially indicate some sort of vulnerability. Finally,
   the information MIB provides about network usage could be used to
   analyze network traffic patterns.

   SNMPv1 by itself is not a secure environment.  Even if the network
   itself is secure (for example by using IPSec), even then, there is no
   control as to who on the secure network is allowed to access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [12] and the View-based
   Access Control Model RFC 2575 [15] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to the objects only to those principals
   (users) that have legitimate rights to indeed GET or SET
   (change/create/delete) them.
