Here's what I'm using for that purpose:
###############################
#!/usr/bin/env python
# Copyright 2004 by Kirk Strauser. BSD licence, etc.
import os
import re
mailboxes = {
'mailserver.example.com':
{ 'ham' : 'INBOX.spam.train.ham',
'spam': 'INBOX.spam.train.spam', }
}
learncmd = 'fetchmail %(options)s --silent --folder %(folder)s --mda "sa-learn
--%(type)s" %(server)s'
printed = None
resre = re.compile(r'Learned from (\d+) message\(s\) \((\d+) message\(s\)
examined\)\.')
totalexamined = totallearned = 0
for server in mailboxes.keys():
for mailtype in mailboxes[server].keys():
# print 'Fetching', mailtype
execcmd = learncmd % {
'folder' : mailboxes[server][mailtype],
'server' : server,
'type' : mailtype,
'options': '',
}
# print execcmd
cmdoutput = os.popen(execcmd).readlines()
if not cmdoutput:
continue
learned = examined = 0
for line in cmdoutput:
result = resre.match(line)
if result:
learned += int(result.group(1))
examined += int(result.group(2))
if not printed:
print 'sa-learn results:'
print
printed = 1
print ' Type:', mailtype
print ' Examined:', examined
print ' Learned :', learned
###############################
I preconfigured fetchmail with my username and password like so:
###############################
poll mailserver.example.com with proto IMAP
user 'myusername' there with password 'password' is 'myusername' here options
fetchall batchlimit 100
###############################
Then, I run the script as a cron job every 15 minutes. It downloads mail
from 'INBOX.spam.train.ham' and uses that for ham training, then repeats
the process for .spam. This is a single-user setup, but you should be
able to extend it pretty easily.
I read my mail with Kmail and drag false positives and negatives into the
appropriate folders as I go.
