NAME

       Mail::SpamAssassin::PersistentAddrList - persistent address list base class

SYNOPSIS

	 my $factory = PersistentAddrListSubclass->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);
	 ...

DESCRIPTION

       All persistent address list implementations, used by the auto-whitelist code to track known-good email addresses, use this as a base class.

       See "Mail::SpamAssassin::DBBasedAddrList" for an example.

METHODS

       $factory = PersistentAddrListSubclass->new();
	   This creates a factory object, which SpamAssassin will call to create a new checker object for the persistent address list.

       my $addrlist = $factory->new_checker();
	   Create a new address-list checker object from the factory. Called by the SpamAssassin classes.

       $entry = $addrlist->get_addr_entry ($addr);
	   Given an email address $addr, return an entry object with the details of that address.

	   The entry object is a reference to a hash, which must contain at least two keys: "count", which is the count of times that address has
	   been encountered before; and "totscore", which is the total of all scores for messages associated with that address.  From these two
	   fields, an average score will be calculated, and the score for the current message will be regressed towards that mean message score.

	   The hash can contain whatever other data your back-end needs to store, under other keys.

	   The method should never return "undef", or a hash that does not contain a "count" key and a "totscore" key.

       $entry = $addrlist->add_score($entry, $score);
	   This method should add the given score to the whitelist database for the given entry, and then return the new entry.

       $entry = $addrlist->remove_entry ($entry);
	   This method should remove the given entry from the whitelist database.

       $entry = $addrlist->finish ();
	   Clean up, if necessary.  Called by SpamAssassin when it has finished checking, or adding to, the auto-whitelist database.
