Summary: spamassassin --add-addr-to-{white,black}list doesn't
work
Product: Spamassassin
Version: SVN Trunk (Latest Devel Version)
Platform: Other
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P5
Component: spamassassin
AssignedTo: [email protected]
ReportedBy: [email protected]
These commands (--add-addr-to-blacklist and --add-addr-to-whitelist) just set
the AWL database with count=1 and totscore equal to to plus or minus 100. But
since the count is set to 1, the average score quickly returns to the mean
typical for messages from this source.
For example, consider a message sender [email protected], whose messages are
flagged as spam with score 30. Assume the system is configured with a spam
threshold of 10. Finally, assume an administrator runs spamassassin
[email protected] and that several messages are then
recieved from this source. We will see the following behaviour:
Message pre-AWL post-AWL count totscore Message accepted?
score score
1 -100
1 30 -35 2 -70 TRUE
2 30 -20 3 -40 TRUE
3 30 -5 4 -10 TRUE
4 30 10 5 20 FALSE
5 30 25 6 50 FALSE
As it turns out, the --add-addr-to-whitelist command was only good for three
messages.
In my opinion, the easy way to fix this bug is to set totscore=100000 and
score=1000, but the best way is to probably have a scheme where if count is
null then totscore is never changed, and to set count=null when adding known
addresses.
