Spam autolearning and spam blacklists

[Michele Neylon :: Blacknight Solutions]

In a word - yes.
If you look in the MailScanner.conf file you will see:
# Spam Detection and Spam Lists (DNS blocklists)
# ----------------------------------------------
#

# Do you want to check messages to see if they are spam?
# Note: If you switch this off then *no* spam checks will be done at all.
#       This includes both MailScanner's own checks and SpamAssassin.
#       If you want to just disable the "Spam List" feature then set
#       "Spam List =" (i.e. an empty list) in the setting below.
# This can also be the filename of a ruleset.
Spam Checks = yes

# This is the list of spam blacklists (RBLs) which you are using.
# See the "Spam List Definitions" file for more information about what
# you can put here.
# This can also be the filename of a ruleset.
Spam List = ORDB-RBL SBL+XBL # MAPS-RBL+ costs money (except .ac.uk)

# This is the list of spam domain blacklists which you are using
# (such as the "rfc-ignorant" domains). See the "Spam List Definitions"
# file for more information about what you can put here.
# This can also be the filename of a ruleset.
Spam Domain List =

# If a message appears in at least this number of "Spam Lists" (as defined
# above), then the message will be treated as "High Scoring Spam" and so
# the "High Scoring Spam Actions" will happen. You probably want to set
# this to 2 if you are actually using this feature. 5 is high enough that
# it will never happen unless you use lots of "Spam Lists".
# This can also be the filename of a ruleset.
Spam Lists To Reach High Score = 5

If you tweak the setting regarding spam lists and your high scoring action
you can easily block spam :)

Subject: [MAILSCANNER] Spam autolearning and spam blacklists

We're seeing a lot of these lately: 
Apr 25 10:33:32 external-smtp MailScanner[23350]: Message 75AE584846 from
4.7.254.117 (lnwbompvnxmso at attorney.ac) to localdomain.com is spam,
spamcop.net, CBL, DSBL, SBL+XBL, SpamAssassin (score=0, required 7,
autolearn=not spam)
This mail is certainly spam, but SpamAssassin doesn't have rules for it and
hence not only gives it a 0 score but autolearns it as not spam. This is, of
course, badly messing with our Bayes database. Is there any way to tell it
(via MailScanner?) that if it hits 1 or more spam blacklists (4 in this
case) it sohuld be autolearned as spam, regardless of SpamAssassin score?
