The delay_warning to the sender is per-message, and the last thing you'd
want as postmaster is to have your mailbox flooded with delay warnings
on every queue hiccup, possibly exacerbating the congestion.
If you want to track delivery latency, use the logs to trigger a consolidated
alert when enough messages are delayed. You can use "postqueue -j", or "qshape"
or a smoothed average from the "delays=" logging...
FWIW, I always disable *all* postmaster notifications.
