      SYNTAX TimeInterval

      SYNTAX INTEGER (-2147483648..2147483647)
      MAX-ACCESS read-only
      STATUS current
      DESCRIPTION
        "Describes how this group fits into the hierarchy. A
         positive value is interpreted as an mtaGroupIndex
         value for some other group whose variables include
         those of this group (and usually others). A negative
         value is interpreted as a group collection code: Groups
         with common negative hierarchy values comprise one
         particular breakdown of MTA activity as a whole. A
         zero value means that this MIB implementation doesn't
         implement hierarchy indicators and thus the overall
         group hierarchy cannot be determined."

         Whenever possible this should be in the form of an
         RFC 822 msg-id; X.400 may convert X.400 message
         identifiers to this form by following the rules laid
         out in RFC2156."

   mtaGroupLoopsDetected OBJECT-TYPE
      SYNTAX Counter32
      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 in conjunction with something associated with

         this group since group creation.  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."
