Fast Bayesian spam filter along lines suggested by Paul Graham

If you think the lexer (the part of bogofilter that breaks out the works from the input) is goofing up, try running bogofilter or bogolexer again, and add -vvvv -xbilmt to the command line. Note that this produces copious output and should not be placed in cron jobs, mail filters, or thereabouts.
The full list of debug flags is in the source tarball in debug.h, excerpt shown below:
#define BIT_NAMES "abcdghilmrstuwyz" #define BIT_ALGORITHM MASK_BIT('A') #define BIT_READER MASK_BIT('B') #define BIT_CONFIG MASK_BIT('C') #define BIT_DATABASE MASK_BIT('D') #define BIT_GENERAL MASK_BIT('G') #define BIT_HTML MASK_BIT('H') #define BIT_ICONV MASK_BIT('I') #define BIT_LEXER MASK_BIT('L') #define BIT_MIME MASK_BIT('M') #define BIT_MULTI MASK_BIT('U') #define BIT_REGISTER MASK_BIT('R') #define BIT_SPAMICITY MASK_BIT('S') #define BIT_TEXT MASK_BIT('T') #define BIT_WORDLIST MASK_BIT('W') #define BIT_MEMORY MASK_BIT('Y') #define BIT_TEST MASK_BIT('Z')
These are the bits you would add to the -x option. For instance, -xl would enable lexer debugging, -xlm would enable lexer and MIME debugging. Whether you use capital or small letters does not matter.
The "-v"s are to raise the output level, some debug output is only generated at high verbosity levels.
