I’m not particularly worried about congestion on this server, but maybe delay
is the wrong warning to focus on - I’d like postmaster notifications for some
temporary bounces, as they can indicate IP reputation rate-limits, which I’d
love to learn about.
Sure, I could write something that parses the smtp logs, but it’d be nice not
to have to.
