    SYNTAX INTEGER (4000000..5999999)
    MAX-ACCESS not-accessible
    STATUS current
    DESCRIPTION
      "An index capable of representing an Enhanced Mail System
       Status Code.  Enhanced Mail System Status Codes are
       defined in RFC 1893 [14].  These codes have the form

           class.subject.detail

       Here 'class' is either 2, 4, or 5 and both 'subject' and
       'detail'  are integers in the range 0..999. Given a status
       code the corresponding index value is defined to be
       ((class * 1000) + subject) * 1000 + detail.  Both SMTP
       error response codes and X.400 reason and diagnostic codes
       can be mapped into these codes, resulting in a namespace
       capable of describing most error conditions a mail system
       encounters in a generic yet detailed way."

    MAX-ACCESS read-only
    STATUS current
    DESCRIPTION
      "A message loop is defined as a situation where the MTA
       decides that a given message will never be delivered to
       one or more recipients and instead will continue to
       loop endlessly through one or more MTAs.  This variable
       counts the number of times the MTA has detected such a
       situation since MTA initialization. Note that the
       mechanism MTAs use to detect loops (e.g. trace field
       counting, count of references to this MTA in a trace
       field, examination of DNS or other directory information,
       etc.), the level at which loops are detected (e.g. per
       message, per recipient, per directory entry, etc.), and
       the handling of a loop once it is detected (e.g. looping
       messages are held, looping messages are bounced or sent
       to the postmaster, messages that the MTA knows will loop
       won't be accepted, etc.) vary widely from one MTA to the
       next and cannot be inferred from this variable."
    ::= {mtaEntry 12}

-- MTAs typically group inbound reception, queue storage, and
-- outbound transmission in some way, rather than accounting for
-- such operations only across the MTA as a whole. In the most
-- extreme case separate information will be maintained for each
-- different entity that receives messages and for each entity
-- the MTA stores messages for and delivers messages to.  Other
-- MTAs may elect to treat all reception equally, all queue
-- storage equally, all deliveries equally, or some combination
-- of this. Overlapped groupings are also possible, where an MTA
-- decomposes its traffic in different ways for different
-- purposes.

-- In any case, a grouping abstraction is an extremely useful for
-- breaking down the activities of an MTA. For purposes of
-- labelling this will be called a "group" in this MIB.

-- Each group contains all the variables needed to monitor all
-- aspects of an MTA's operation.  However, the fact that all
-- groups contain all possible variables does not imply that all
-- groups must use all possible variables. For example, a single
-- group might be used to monitor only one kind of event (inbound
-- processing, outbound processing, or storage). In this sort of
-- configuration all unused counters would be inaccessible; e.g.,
-- returning either a noSuchName error (for an SNMPv1 get), or a
-- noSuchInstance exception (for an SNMPv2 get).

-- Groups can be created at any time after MTA initialization. Once
-- a group is created it should not be deleted or its mtaGroupIndex
-- changed unless the MTA is reinitialized.

-- Groups are not necessarily mutually exclusive. A given event may
-- be recorded by more than one group, a message may be seen as
-- stored by more than one group, and so on.  Groups should be all
-- inclusive, however: if groups are implemented all aspects of an
-- MTA's operation should be registered in at least one group. This
-- freedom lets implementors use different sets of groups to
-- provide differents "views" of an MTA.

-- The possibility of overlap between groups means that summing
-- variables across groups may not produce values equal to those in
-- the mtaTable. mtaTable should always provide accurate information
-- about the MTA as a whole.

-- The term "channel" is often used in MTA implementations; channels
-- are usually, but not always, equivalent to a group. However,
-- this MIB does not use the term "channel" because there is no
-- requirement that an MTA supporting this MIB has to map its
-- "channel" abstraction one-to-one onto the MIB's group abstration.

-- An MTA may create a group or group of groups at any time. Once
-- created, however, an MTA cannot delete an entry for a group from
-- the group table.  Deletation is only allowed when the MTA is
-- reinitialized, and is not required even then.  This restriction
-- is imposed so that monitoring agents can rely on group
-- assignments being consistent across multiple query operations.

-- Groups may be laid out so as to form a hierarchical arrangement,
-- with some groups acting as subgroups for other groups.
-- Alternately, disjoint groups of groups may be used to provide
-- different sorts of "snapshots" of MTA operation.  The
-- mtaGroupHierarchy variable provides an indication of how each
-- group fits into the overall arrangement being used.
