I have a recipe that filters traffic reports delivered to me in the
afternoon one hour intervals. I only want to see reports with accidents,
slowdowns, and traffic advisories in locations along my commute, and not
those with only scheduled road work. The recipe deletes reports that
don't contain locations along my commute as well as reports about road
work in those cities unless there are accidents, slowdowns, advisories
in those cities. This recipe use to work until mid-April. Then it
started failing and it would deliver reports with only road work in
those cities instead of deleting them. The weird thing is that the
recipe works when I subsequently debug the problem in a test directory
on my IMAP/file server after erroneous delivery.
Does anyone know why procmail behaves inconsistently between production
mode and test mode (see the diagnostic output below)? The IMAP server
may have recently had a sendmail patch applied, but I don't know if that
is related in any way. The platform is procmail 3.15.2 on Solaris 9.
The scoring recipe, part of a sample traffic report, and the diagnostic
outputs in production mode (incorrect) and debug mode (correct) are
included below.
