Tom,

Take a look at tuning/bogotune or at contrib/bogotrain.pl to see
successful use of bogofilter from perl.

Strings can definitely be passed to bogofilter:

[relson at osage src]$ echo this is a test | bogofilter -vvv -d
/var/lib/bogofilter
X-Bogosity: No, tests=bogofilter, spamicity=0.415000, version=0.15.4
                                     n    pgood     pbad      fw     U
"head:test"                          0  0.000000  0.000000  0.415000 -
"head:this"                          0  0.000000  0.000000  0.415000 -
N_P_Q_S_s_x_md                       0  0.00e+00  0.00e+00  4.15e-01
                                        1.00e-02  4.15e-01  0.100

Bogofilter's output is generally to stdout.  stderr is used for error
and debug messages.  Command line flag "-D" can be used to direct the
messages to stdout.
