Greetings,
I retrained bogofilter with my accumulated mail, which goes back to last
October, using the current defaults. Here are the word counts:
spam ham
old 122,006 325,455
new 180,587 382,635
It appears that case sensitivity and header line tagging had almost
identical effects for the two wordlist, i.e. added approx 58,000 tokens to
each.
David
