Here's an update:
I found a seemingly unrelated problem. I had duplicated the
notify-host-by-email command into the notify-service-by-email command.
While this accounted for the inappropriate message content, fixing it
seems to have also fixed the repeating notifications (haven't received
any in a while).
No idea why fixing the invalid message text would also fix the
repeating notifications, but it seems OK now.
I'm posting the answer here in case anybody else runs into this problem.
The lines below are working nicely on a system that uses postfix as
the mailer.
This also takes care of postix's sendmail not respecting the -s
(subject) command line option. The macros below add the subject to the
message.
