Nigel before going any further in discussing efficiency of your proposed 
filtering system I have attached my file "bogofilter.cf" that is part of my 
setting ; may be there is something wrong in it as after 4 days of absence I 
collected plenty of spam mail in my inbox.
Regards.

########### General Settings ########################################

#### BOGOFILTER_DIR
#
#	directory for wordlists
#
bogofilter_dir=~/.bogofilter
##bogofilter_dir=/var/spool/bogofilter

#### TRANSACTIONS: enable/disable database transactions
#
#	boolean indicating whether transactions
#	should be enabled (yes) or disabled (no)
#
db_transaction=no		# default
##db_transaction=yes		# (alternate)

#### WORDLIST: define additional word lists
#
#	char type: 'r' (regular) or 'i' (ignore)
#	char *name: name of list, e.g. "system", "user", "ignore"
#	char *path: absolute path to file or
#		    file name (relative to bogofilter_dir)
#	int  order - once found, skip higher numbered lists
#
##wordlist i,ignore,~/ignorelist.db,1
##wordlist r,wordlist,~/wordlist.db,2

#### SPAM_HEADER_NAME
#
#	used in reporting spamicity and
#	in removing already existing headers
#
spam_header_name=X-Bogosity

#### 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???

#### STATS_IN_HEADER
#
#	non-zero (default):  put spamicity info in message header
#	zero:  put spamicity info in message body
#	can use "bool" values of True, False, Yes, No, 1, or 0
#
stats_in_header=Yes		# default
##stats_in_header=No		# (alternate)

#### DB_CACHESIZE
#
#	non-zero: set this as DB cache size (in Mbytes)
#	zero:     use DB default cache size (.25 Mbyte in 4.0.14)
#
#	note that Berkeley DB increases any buffer size below 500 MB
#	by 25%!
#	This helps most when doing massive changes to the data base that
#	involve a lot of overwrites, such as registering mail boxes,
#	whereas it is mostly a waste of memory for read-only
#	applications such as scoring.
#	WARNING: If you set this too large, bogofilter will fail.

#

#### Format of SPAM_HEADER
#
#	formatting characters:
#
#	    h - spam_header_name, e.g. "X-Bogosity"
#
#	    c - classification, e.g. Yes/No, Spam/Ham/Unsure, +/-/?
#
#	    D - date, fixed ISO-8601 format for Universal Time ("GMT")
#
#	    e - spamicity as 'e' format
#	    f - spamicity as 'f' format
#	    g - spamicity as 'g' format
#
#	    A - IP address (from first Received: statement having one)
#		Not guaranteed to be the originating address of the message.
#	    I - Message ID
#	    Q - Queue ID (from first id tag found in Received: headers)
#
#	    l - logging tag (from '-l' option)
#
#	    o - spam_cutoff, ex. cutoff=%o
#
#	    p - spamicity value
#	    d - if ham or unsure, the spamicity
#		if spam, difference of spamicity from 1.0
#
#	    r - runtype

#		the message header and '-v' outputs.
#	terse_format - an abbreviated form of header_format;
#		selected by command line option '-t'
#	log_header_format - written to syslog by '-u' option
#		when classifying messages.
#	log_update_format - written to syslog by '-u' option
#		when registering messages.
