mailbox classification not working right

[Barry Gould]

Hi,

With Bogofilter 0.10.0, using Robinson-Fisher ternary:

I just fed a mailbox full of spam to bogofilter -s, and, although it did 
register the mail, I do not believe it is doing it correctly.

I believe it is treating the entire mailbox as only a few messages. (more 
evidence below)

The reason I am complaining about this is that it is not doing a good job 
registering the messages as spam. If I take a single "Unknown" (spamicity 
0.36 or so) message from the mailbox and register it, the Spamicity 
immediately goes to 1.0000, but if I register the mailbox, it only changes 
VERY slightly.

I read part of the recent "mailbox classification" discussion; I understand 
Formail may be recommended in the future, but it seems like it needs to be 
recommended for 0.10.0 as well.

BTW, I registered all my corpora several months ago this way; I wonder now 
if it didn't work right then either.

Thanks,
Barry

more evidence:
"webmaster" is a linux mailbox which contains 26 spam messages, some of 
which were unknowns or false negs.

# grep Subject\: webmaster|wc -l
      26
# grep From\: webmaster|wc -l
      26

# bogoutil -w .bogofilter/ .MSG_COUNT
                        spam   good
.MSG_COUNT            10185  32689

# bogofilter -s < webmaster

# bogoutil -w .bogofilter/ .MSG_COUNT
                        spam   good
.MSG_COUNT            10190  32689
