Message delay warning messages

This has come up before when I was running PP on my mail hubs. At the
time I probably thought that sending warnings after (by default) 24 hours
was a PP idea, but now I have moved to running Exim on my two mail hubs
and that does the same thing by default. Is this still a minority
behaviour? Otherwise I would expect mailing-list owners like the one who
mailed me the above message to be used to seeing them?

The sending of such warnings can also create a lot of traffic locally...
Last weekend a scheduled power cut meant that several important mail hosts
had to be shut down for about 64 hours. This caused an awful lot of
warning messages to be generated (from postmaster@???).
However, many of these were generated by undelivered SPAM and so could not
be delivered; consequently the site postmaster received hundreds of
non-delivery reports. (I have started using a SPAM filter, but it will
never catch it all.)

There is another scheduled powercut this weekend. So any advice on the
use of message delay warnings would be most gratefully received!
