toaster-watcher.pl - monitors and configure various aspects of a qmail toaster
toaster-watcher does several unique and important things. First, it includes a configuration file that stores settings about your mail system. You configure it to suit your needs and it goes about making sure all the settings on your system are as you selected. Various other scripts (like toaster_setup.pl) and programs use this configuration file to determine how to configure themselves and other parts of the mail toaster solution.
The really cool part about toaster-watcher.pl is that it dynamically builds the run files for your qmail daemons (qmail-smtpd, qmail-send, and qmail-pop3). You choose all your settings in toaster-watcher.conf and toaster-watcher.pl builds your run files for you, on the fly. It tests the RBL's you've selected to use, and builds a control file based on your settings and dynamic information such as the availability of the RBLs you want to use.
We first build a new $service/send/run file based on your settings in toaster-watcher.conf. There are a ton of configuration options, be sure to check out the docs for toaster-watcher.conf.
If the new generated file is different than the installed version, we install the updated run file and restart the daemon.
We first build a new $service/pop3/run file based on your settings in toaster-watcher.conf. There are a ton of configuration options, be sure to check out the docs for toaster-watcher.conf.
We first build a new $service/smtp/run file based on your settings in toaster-watcher.conf. There are a ton of configuration options, be sure to check out the docs for toaster-watcher.conf.
We first build a new $service/submit/run file based on your settings in toaster-watcher.conf. There are a ton of configuration options, be sure to check out the docs for toaster-watcher.conf.
This script runs the clearopensmtp program which expires old ip addresses from the vpopmail smtp relay table. It will only run if you have vpopmail_roaming_users enabled in toaster-watcher.conf.
If you have isoqlog installed, you'll want to have it running frequently. I suggest running it from here, or from cron directly.
Qmail-Scanner quarantines any files that fail certain tests, such as banned attachments, Virus laden messages, etc. The messages get left laying around in the quarantine until someone does something about it. If you enable this feature, toaster-watcher.pl will go through the quarantine and deal with messages as you see fit.
I have mine configured to block the IP (for 24 hours) of anyone that's sent me a virus and delete the quarantined message. I run toaster-watcher.pl from cron every 5 minutes so this usually keeps virus infected hosts from sending me another virus laden message for at least 24 hours, after which we hope the owner of the system has cleaned up his computer.
Many times its useful to have a script that cleans up old mail messages on your mail system and enforces policy. Now toaster-watcher.pl does that. You tell it how often to run (I use every 7 days), what mail folders to clean (Inbox, Read, Unread, Sent, Trash, Spam), and then how old the messaged need to be before you remove them.
I have my system set to remove messages in Sent folders more than 180 days old and messages in Trash and Spam folders that are over 14 days old. I have also instructed toaster-watcher to feed any messages in my Spam and Read folders that are more than 1 day old through sa-learn. That way I train SpamAssassin by merely moving my messages into appropriate folders.
Feature request by David Chaplin-Leobell: check for low disk space on the queue and mail delivery partitions. If low disk is detected, it could either just notify the administrator, or it could do some cleanup of things like the qmail-scanner quarantine folder.
