We also monitor -

CPU, Memory, filesystems, load average, swap activity, mail queues
(active and deferred), mail throughput in messages/min (passed, spam,
virus) plus a detailed analysis of the virus types and spam rules,
greylisting activity and database size, tcp ports for each mail input
and relay stage, SMTPS SSL certificate expiry, active users, active
connections, time taken for a test email to pass through the system,
number of mail processes (postfix, amavis, gld), virus scanner daemons,
mail cluster activity, performance, and failover.

Plus most of this is also graphed where possible.
