MTA counters

The MTA has facilities to collect and monitor channel counters based upon the Mail Monitoring MIB, RFC 2789 (which updates RFC 1566). Note that counters are intended for providing real-time "snap-shots" of MTA behavior, rather than for gathering the sort of statistics instead available from the MTA transaction log files. For a description of the MTA channel counters, see MTA channel counters.

New in 8.0, the MTA also maintains eight signed, 64 bit counters intended for updating from within Sieve scripts, for site-customizable use; see the  Sieve adjustcounter extension.

The MTA provides utilities  to display the counters directly; see the    and    utilities.
