#
#   Overview of features
#
#       o   To detect spam reliably, run all Bayesian programs one by one
#           to see if any of them classifies the message as spam.
#       o   Programs supported: bogofilter, spamprobe, Bayesian Mail
#           Filter, Annoyance Filter, Bsfilter, Spamoracle and Spamassassin.
#
#   Description
#
#       There are several bayesian based statistical analysis programs that
#       study the message's tokens and then classify it into two categories:
#       good or bad, or if you like, ham and spam. This module is a
#       _meta_ _package_ which will call all other individual modules
#       that interface to these Bayesian programs. The use is simple: define
#       programs that are available in your system and which you have
#       trained (Bayesian programs need to be trained before use), and this
#       this module will query how those programs would classify the message.
#
#   Required settings
#
#       PMSRC must point to source directory of procmail code. This subroutine
#       will include
#
#       o   pm-javar.rc
#       o   pm-jaube-prg-spamprobe.rc
#       o   pm-jaube-prg-spamoracle.rc
#       o   pm-jaube-prg-annoyance-filter.rc
#       o   pm-jaube-prg-bsfilter.rc
#       o   pm-jaube-prg-bmf.rc
#
#   Call arguments (variables to set before calling)
#
#       To activate Bayesian program(s), define path to them. Default
#       value for all these variables is "" i.e. is is supposed that
#       no programs have been installed or trained.
#
#       o   `JA_UBE_BOGOFILTER_PRG', path to *bogofilter* program.
#       o   `JA_UBE_SPAMPROBE_PRG', Path to *spamprobe* program
#       o   `JA_UBE_BMF_PRG', Path to Bayesian Mail Filter *bmf* program.
#       o   `JA_UBE_SPAMASSASSIN_PRG', path to *spamassassin* program.
#           If daemon version is available, set this to *spamc* program.
#       o   `JA_UBE_SPAMORACLE_PRG', path to *spamoracle* program.
#       o   `JA_UBE_ANNOYANCE_PRG', path to *annoyance-filter* program.
#           You must also set `JA_UBE_ANNOYANCE_SPAM_DB' to fast
#           dictionary database location.
#       o   `JA_UBE_BSFILTER_PRG', path to *bsfilter* program.
#
#       Optional variables to set:
#
#       o    `JA_UBE_BOGOFILTER_OPT'. Default is "-p" passthrough.
#            Option "-e" will report exit code to procmail.
#       o    `JA_UBE_SPAMASSASSIN_OPT'. Default is "".
#       o    `JA_UBE_SPAMASSASSIN_MAX_SIZE'. Default is 256000 (256k).
#            Spamassassin is a Perl program, which is slow at startup,
#            so checking e.g. long attachements consumes lot of resources.
#            Keep this value relatively small.
#
#   Important notes
#
#       All headers are canonicalized to *X-Spam-<PROGRAM>-* so e.g.
#       in bogofilter's case, the default *X-Bogocity* header is
#       changed to value *X-Spam-Bogofilter-Status* and so on.
#       Summaries like below can then be generated:
#
#           $ egrep -i '(Subject|From|^X-Spam.*Status)' *.mbox
#
#   Return values
#
#       o   `ERROR' variable's first word is set to program that classified
#           the spam: *bogofilter*, *bmf* (Bayesian Mail Filter),
#           *spamassassin* etc. It is followed by semicolon ";" and
#           detailed return status from the program.
#       o   `ERROR_INFO' is set only in bogofilter's case if it thinks
#           the message is neither spam nor ham ("Unsure").
#
#   Usage example
#
#           PMSRC                 = $HOME/procmail # procmail recipe dir
#
#           # ... other checks, mailing lists, work mail etc.
#
#           #   bogofilter and Bayesian Mail Filter available and trained. Use them.
