[S-mailx] bogofilter wuestion

[Χάρης Καραχριστιανίδης]

I installed bogofilter and put these lines in .mailrc.
set spam-interface=filter
set spam-maxsize=500000
set spamfilter-ham="bogofilter -n"
set spamfilter-noham="bogofilter -N"
set spamfilter-nospam="bogofilter -S"
set spamfilter-rate="bogofilter -TTu 2>/dev/null"
set spamfilter-spam="bogofilter -s"
set spamfilter-rate-scanscore="1;^(.+)$"
set headline='%>%a%m%$ %-18f %16d %4l/%-5o %i%-s'

With:
? spamrate 1-31
I get
spamrate:.31          1/30     done (31/0 all/skipped)

and nothing changes in emails spam rate, all are 0.00.

If I run
? spamspam 28
nothing changes again.
Any help please?
