I changed that to:
bogoutil -p wordlist.db rcvd:Jan rcvd:Feb rcvd:Mar rcvd:Apr rcvd:May
rcvd:Jun rcvd:Jul rcvd:Aug rcvd:Sep rcvd:Oct rcvd:Nov rcvd:Dec
and:
bogoutil -p wordlist.db head:Jan head:Feb head:Mar head:Apr head:May
head:Jun head:Jul head:Aug head:Sep head:Oct head:Nov head:Dec

These two lists were quite different, and different from the first one too.
And both of them have months which are very hammy or very spammy, but not
always the same ones.  For example, rcvd:Jan has 158793 spam and 1131 ham
for a score of 0.826102, while head:Jan has 3818 spam and 1314 ham for a
score of 0.089524.  Neither of these ought to be so biased.  Even if
spammers are inserting fake recieved lines with Jan in them most of the
time, I still don't want this to detract from the hams I get in January.
Nor do I want the fact that I generally receive more spam than ham to make
hams seem more spammy in other months.  All dates should be ignored I think.
