Hi
spam-fighters,
What do you think
about a time-dependently hold weight?
Maybe this can be
helpfull on certain systems (where all users work in the same time zone) to
reduce FP's.
For further
explanation please see the PDF-file located at www.zcom.it/decludeupdater/returncodes.pdf
(280 kB).
-The red dots are
single messages over 24 hours (x) and their weight (y).
-The blue line is
the average value of all weights in this time range
-The yellow line is
our current hold weight of 100 points.
(consider it 100% if you hold on the default weight of 20 points)
(consider it 100% if you hold on the default weight of 20 points)
Now my
suggestion/question:
As you can see, our
server processes most legit messages between 8:00 AM and 8:00
PM
So why not increase
the hold weight slightly in this time range and decrease it a little bit on the
resting time? (green line)
Counting our FP's
from the last 20 days and increasing the hold weight during business time from
100 to 110 this will avoid 65% of them.
Naturally the
increased hold value let pass some more spam messages, but with 225 more
delivered spam (that has recieved a weight between 100 and 110 points) from
over 14000 hold spam in the last 20 days this is very few.
Theoretically we all
can create two identical configuration files with 2 different hold weights and
switch between this two with a scheduled task. No additional ressources are
needed.
...or am I missing
something?
