1. Don't send bounces to postmaster, just generate and read log summaries
that may highlight aggregate problems with your mail stream.
notify_classes =
This applies to any MTA handing mail for a large number of users,
it is fine to have postmaster notices for a machine with a small
handful of users, but after than postmaster notices are just a waste
of time and focus your attention on the wrong things (reading bounces
of other people's mail).
The logs not the postmaster mailbox are your notices of trouble.
2. When problems happen. READ THE LOGS.
