What is Unsure mode?
Bogofilter's default configuration will classify a message as spam or
non-spam. The SPAM_CUTOFF parameter is used for this. Messages with
scores greater than or equal to SPAM_CUTOFF are classified as spam.
Other messages are classified as ham.

There is also a HAM_CUTOFF parameter. When used, messages must have
scores less than or equal to HAM_CUTOFF to be classified as ham.
Messages with scores between HAM_CUTOFF and SPAM_CUTOFF are classified
as unsure. If you look in bogofilter.cf, you will see the following
lines:

    #### CUTOFF Values
    #
    #    both ham_cutoff and spam_cutoff are allowed.
    #    setting ham_cutoff to a non-zero value will
    #    enable tri-state results (Spam/Ham/Unsure).
    #
    #ham_cutoff  = 0.45
    #spam_cutoff = 0.99
    #
    #    for two-state classification:
    #
    ## ham_cutoff = 0.00
    ## spam_cutoff= 0.99

To turn on Yes/No/Unsure classification, remove the #'s from the last
two lines.

Alternatively, if you'd rather use labels Yes/No/Unsure instead of
Spam/Ham/Unsure, remove the #'s from the following bogofilter.cf line: 

    ## spamicity_tags = Yes, No, Unsure

Once that's done, you may want to set the filtering rules for your mail
program to include rules like:

    if header contains "X-Bogosity: Spam", put in Spam folder
    if header contains "X-Bogosity: Unsure", put in Unsure folder

Alternatively, bogofilter.cf has directives for modifying the Subject:
line, i.e.

    #### SPAM_SUBJECT_TAG
    #
    #    tag added to "Subject: " line for identifying spam or unsure
    #    default is to add nothing.
    #
    ##spam_subject_tag=***SPAM***
    ##unsure_subject_tag=???UNSURE???

With these subject tags, the filtering rules would look like:

    if subject contains "***SPAM***", put in Spam folder
    if subject contains "???UNSURE???", put in Unsure folder
