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.
