Usage

Overview

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".

Options

--clean

Clean out infrequently-used AWL entries. The "--min" switch can be used to select the threshold at which entries are kept or deleted.

--dry-run

When specified with th "--clean" option it displays the infrequently-used AWL entries that will be deleted. 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.

Output

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.
