Re: patch to add classifying threshold

Hi Paolo,

I did implement something roughly similar on my MDA, but outside of 
ifile (I take the first two lines of the standard output result and do 
the diff). Wasn't it possible to do that with procmail ?

Do you use more than two categories (spam, ham) ? In that case how do 
you deal this all the in-between categories (A, B, C, between A and B... 
between C and B), as all the possible combinations becomes quickly 
unmanagable, isn't it ?

BTW, I use fetchmail to take my emails from my accounts and I have a 
custom MDA (a shell script that uses ifile and writes the message into 
the proper Maildir with the proper name). It still beta and I'd like to 
add a few features. Anyone interested by a doc and the code ?

Xavier

P.S. The patch file Paolo mention is downloadable at
