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 out infrequently-used AWL entries. The --min switch can be used to select the threshold at which entries are kept or deleted.
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=IPBASEFor example:
0.0 (0.0/7) -- dawson@example.com|ip=208.192
21.8 (43.7/2) -- mcdaniel_2s2000@example.com|ip=200.106AVG 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.
