sa−awl − examine and manipulate SpamAssassin’s auto−whitelist db
sa-awl [−−clean] [−−min n] [dbfile]
Check or clean a SpamAssassin auto-whitelist (AWL) database file.
The name of the file is specified after any options, as "dbfile". The default is "$HOME/.spamassassin/auto−whitelist".
−−clean
Clean out infrequently-used AWL entries. The "−−min" switch can be used to select the threshold at which entries are kept or deleted.
−−min n
Select the threshold at which entries are kept or deleted when "−−clean" is used. The default is 2, so entries that have only been seen once are deleted.
The output looks like this:
AVG (TOTSCORE/COUNT) −− EMAIL|ip=IPBASE
For example:
0.0 (0.0/7)
−− [email protected]|ip=208.192
21.8 (43.7/2) −−
[email protected]|ip=200.106
"AVG" is the average score; "TOTSCORE" is the total score of all mails seen so far; "COUNT" is the number of messages seen from that sender; "EMAIL" is the sender’s email address, and "IPBASE" is the AWL base IP address.
AWL base IP address is a way to identify the sender’s IP address they frequently send from, in an approximate way, but remaining hard for spammers to spoof. The algorithm is as follows:
− take the
last Received header that contains a public IP address
−− namely
one which is not in private, unrouted IP space.
− chop off the last two octets, assuming that the user
may be in an ISP's
dynamic address pool.
