sa-awl - examine and manipulate SpamAssassin's auto-welcomelist db
sa-awl [--clean] [--min n] [dbfile]
Check or clean a SpamAssassin auto-welcomelist (AWL) database file.
The name of the file is specified after any options, as "dbfile". The default is "$HOME/.spamassassin/auto-welcomelist".
- 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
0.0 (0.0/7) -- email@example.com|ip=208.192 21.8 (43.7/2) -- firstname.lastname@example.org|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.
