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

  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);

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-welcomelists.

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 '',
msgcount 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:






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

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.

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.

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.

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.

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.

public instance () finish ()

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

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

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