NAME

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

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(16) 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.
