It is most useful for people who are subscribed to mailing +lists to help organize their messages. The argument stands that filtering is +not the place of the client, which is why this has been made a plugin for +SquirrelMail. You may be better off using products such as Sieve, Maildrop or +Procmail to do your filtering so it happens even when SquirrelMail isn't +running. IMPORTANT: At least one version of PHP has bugs in the checkdnsrr() function that the SPAM filtering code RELIES ON. The PHP server that comes with Mandrake 8.1 has this problem -- checkdnsrr() NEVER finds the inaddr records, even the ones that really exist. -NOTE!!! As of the time of this writing, there is a bug in sqimap_read_data() in -functions/imap_general.php. I rewrote it (see sqimap_read_data.php) so if the -SPAM filters aren't filtering, make a backup copy of functions/imap_general.php, -remove the sqimap_read_data() function in there and replace it with the contents -of sqimap_read_data.php. Hopefully, either my replacement will be blessed by -squirrelmail-devel or some other version will come out soon. Now back to your -regularly scheduled README... (grin) - This is a poor alternative to procmail or Elm's filter programs. This is a pathetic replacement for good RBL mail scanning when you get the mail.

This is slow. Yep. Slow. -To configure, first you need to rename config.sample.php to config.php. You -should then just take a peek at config.php and set $SpamFilters_YourHop to some -string if you want to avoid tons of false hits on the RSS and DUL and ORBS -databases. It should also speed up the scan somewhat. - -If you do not want to enable spam filters for all users, edit config.php and set -the $AllowSpamFilters to false. Spam filters can take TONS of time, so if you -don't want your users to complain and ask you tons of questions, this is a quick -and easy method. +INSTALLATION +------------ +Plugin is installed by enabling it in SquirrelMail configuration script. +Plugin configuration can be changed with configuration files stored in +config/filters_config.php or plugins/filters/config.php. Default configuration +values can be found in plugins/filters/config_default.php. If both +configuration files are present, plugin uses file from config directory. + +Main configuration option that must be changed is $SpamFilters_YourHop setting. +See comments about it in config_default.php. If $SpamFilters_YourHop uses +default value, plugin will be unable to use RBL filtering correctly and +warning message will is displayed to end user. If you don't want to use RBL +filtering, you can disable it by setting $AllowSpamFilters option to false. If +you can control your incoming SMTP server, it is recommended to turn RBL +filtering on server.
