5. Changes made since RFC2249
This revision corrects a number of minor technical errors in the
construction of the mail monitoring MIB in RFC2249 [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 RFC1566 [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.
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 RFC2574 [12] and the View-based
Access Control Model RFC2575 [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.
