NAME

Mail::SpamAssassin::SQLBasedAddrList - SpamAssassin SQL Based Auto Whitelist

CONTENTS

SYNOPSIS



    my $factory = Mail::SpamAssassin::SQLBasedAddrList->new()
    $spamtest->set_persistent_addr_list_factory ($factory);
  ... call into SpamAssassin classes...



SpamAssassin will call:



    my $addrlist = $factory->new_checker($spamtest);
    $entry = $addrlist->get_addr_entry ($addr, $origip);
  ...



DESCRIPTION

A SQL based persistent address list implementation.

See Mail::SpamAssassin::PersistentAddrList for more information.

Uses DBI::DBD module access to your favorite database (tested with MySQL, SQLite and PostgreSQL) to store user auto-whitelists.

The default table structure looks like this: CREATE TABLE awl (
username varchar(100) NOT NULL default ’’,
email varchar(255) NOT NULL default ’’,
ip varchar(40) NOT NULL default ’’,
count int(11) NOT NULL default ’0’,
totscore float NOT NULL default ’0’,
signedby varchar(255) NOT NULL default ’’,
PRIMARY KEY (username,email,signedby,ip) ) TYPE=MyISAM;

Your table definition may change depending on which database driver you choose. There is a config option to override the table name.

This module introduces several new config variables:

user_awl_dsn

user_awl_sql_username

user_awl_sql_password

user_awl_sql_table

user_awl_sql_override_username

see Mail::SpamAssassin::Conf for more information.

    new

public class (Mail::SpamAssassin::SQLBasedAddrList) new ()

Description: This method creates a new instance of the SQLBasedAddrList factory and calls the parent’s (PersistentAddrList) new method.

    new_checker

public instance (Mail::SpamAssassin::SQLBasedAddrList) new_checker (\% $main)

Description: This method is called to setup a new checker interface and return a blessed copy of itself. Here is where we setup the SQL database connection based on the config values.

    get_addr_entry

public instance (\%) get_addr_entry (String $addr, String $signedby)

Description: This method takes a given $addr and splits it between the email address component and the ip component and performs a lookup in the database. If nothing is found in the database then a blank entry hash is created and returned, otherwise an entry containing the found information is returned. If a with_awl_signer configuration option is enabled only addresses signed by the given signing identity are taken into account, or, if $signedby is undefined (or empty) only unsigned entries are considered.

A key, exists_p, is set to 1 if an entry already exists in the database, otherwise it is set to 0.

    add_score

public instance (\%) add_score (\% $entry, Integer $score)

Description: This method adds a given $score to a given $entry. If the entry was marked as not existing in the database then an entry will be inserted, otherwise a simple update will be performed.

NOTE: This code uses a self referential SQL call (ie set foo = foo + 1) which is supported by most modern database backends, but not everything calling itself a SQL database.

    remove_entry

public instance () remove_entry (\% $entry)

Description: This method removes a given $entry from the database. If the ip portion of the entry address is equal to none then remove any perl-IP entries for this address as well.

    finish

public instance () finish ()

Description: This method provides the necessary cleanup for the address list.

    _unpack_addr

private instance (String, String) _unpack_addr(string $addr)

Description: This method splits an autowhitelist address into it’s two components, email and ip address.
