I have modified Martin's scripts ifile.inject-learn.header and
ifile.relearn.message to create a new empty temporary file in two
different directories every time they are called.

So, for example, in ifile.inject-learn.header, the last line is

mktemp /home/jack/.ifile.stats/learned/lXXXXXX >/dev/null 2>/dev/null

If I didn't do anything else, this would give me two directories one
which contained a file for every message, and one which contained a file
for every incorrect message.  Doing a ls | wc -l would therefore be
enough to generate the list below on a total basis.

What I actually do is to use a script ifile.stats.count which is run
nightly after refile.learn, which counts up the messages from the
previous day and stores them in a couple of files, one of which keeps
the current total, and one of which keeps a record of historic totals.
The script emails me a short summary of success rates over the last day
and since records began.  I don't keep track of statistics for an
individual folder - although I could do by counting the number of
X-Ifile-Learned-To headers and subtracting from the number of emails.

I attach the script below for your reference.

The output in my previous email was just a Perl one-liner which took the
contents of the last 30 days of each of the historic record files and
processed them.
