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 NOT NULL, email VARCHAR NOT NULL, ip VARCHAR NOT NULL, count INT NOT NULL, totscore FLOAT NOT NULL, PRIMARY KEY (username, email, ip) ) You're 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 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) 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. 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.
