Note that this change is not strictly supported by SMIv2. However, the alternative of deprecating the old objects and defining new objects would have a more adverse impact on backward compatibility and interoperability, given the particular semantics of these objects. The defining reference for distinguished names has also been updated from RFC 1779 to RFC 2253." REVISION "199905120000Z" DESCRIPTION "This revision fixes a number of technical problems found in previous versions: The conformance groups for different versions of this MIB have been corrected, 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, and the required mtaStatusCode entry has been added to MtaGroupErrorEntry. It should be noted that this last change in no way affects the bits on the wire." REVISION "199708170000Z" DESCRIPTION "This revision, published in RFC 2249, adds the mtaGroupDescription and mtaGroupURL fields, conversion operation counters, a group hierarchy description mechanism, counters for specific errors, oldest message IDs, per-MTA and per-group loop counters, and a new table for tracking any errors an MTA encounters."

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 any counters that are unused as a result of a -- given MTA's use of the group construct must 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 different "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 abstraction. -- 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. Deletion 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. -- Note that SNMP also defines and uses term "group". MTA groups are -- NOT the same as SNMP groups. mtaGroupTable OBJECT-TYPE SYNTAX SEQUENCE OF MtaGroupEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The table holding information specific to each MTA group." ::= {mta 2} mtaGroupEntry OBJECT-TYPE SYNTAX MtaGroupEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The entry associated with each MTA group."
