Filters Plugin
-IMPORTANT: I've noticed at least one version of PHP that has bugs in the
-checkdnsrr() function that the SPAM filtering code RELIES ON. In my case,
-the PHP server that comes with Mandrake 8.1 has this problem -- checkdnsrr()
-NEVER finds the inaddr records, even the ones that really exist. (sigh)
-
-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 more for systems that can't/won't offer that kind of functionality and
-you still require it.
-
-This is slow. Yep. Slow.
-
-
-To configure, you should just take a peek at setup.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 setup.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.

-If you use UW and if you encounter strange errors while using this plugin on
-your system, edit setup.php and set $UseSeparateImapConnection to true. This
-may not solve the problem. One problem it might fix is if you run UW 2001

-pane, or if you see timeouts or IMAP server error messages. Turning on this

+ABOUT PLUGIN
+------------
+This plugin sorts messages in your inbox into different folders based upon
+given criteria. 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.

+that the SPAM filtering code RELIES ON. The PHP server that comes with Mandrake

+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.
+
+If you use UW and if you encounter strange errors while using this plugin on
+your system, edit configuration file and set $UseSeparateImapConnection to
+true. This may not solve the problem. One problem it might fix is if you run UW
+2001 and if you don't see the number of unread messages in your left-hand
+folder pane, or if you see timeouts or IMAP server error messages. Turning on
+this feature may slow down the filters a bit more since it has to open a new
connection.
-Lastly, if there are some IPs that you want to refuse email from or some IPs
-you want to accept email from REGARDLESS of what the DNS databases say, you
-can put in overrides in the SpamFilters_DNScache[] array. See the comments
-in setup.php for more info on this.
