vBouncer: reduce server load by unsubscribing bouncing members from threads
Developer Last Online: Nov 2023
vBouncer is a handy tool for busy forums (or those that do not require email verification) to control the amounts of bogus emails sent from and to your server.
What vBouncer does: vBouncer monitors your mail spool file, and identifies members responsible for large amounts of bounced emails. It then issues a PM warning, and when the unsubscribe threshold is met, it will will unsubscribe them for all threads, and sets them to the "no email" subscription level. After a couple of runs, this should significantly reduce your server load. Features: o Manual or auto processing option o Collect logs via IMAP/POP or mail spool file o Custom filters to match patterns in bounced emails o Uses vB's cron files (Scheduled tasks) o Uses encrypted header for authentication (suggested by Paul M). o Stats on members with bouncing emails, and error codes o Tuning options o Verbose cron logs for diagnostics o Option to send PM warning prior to reaching the limit o Option to send PM notifications after reaching the limit o Option to change the member's subscription default o Option to all thread subscriptions to "no email" o Option to all forum subscriptions to "no email" o Option to move offenders to a different primary usergroup o Option to process 5.0.0/550 errors (email unknown) upon a single email, isntead of observing the bounce limit Installation: 1. Extract the files into the corresponding directories (admincp => admincp, includes => includes) 2. Run the installation script in the admincp 3. Fill out the settings menu in the vBouncer section of the admin panel (see the how-to post below) 4. Import and activate the plugin file through the plugin manager. 5. Once ready, add the cron scripts to your scheduled tasks: vbouncer-collect.php (should be run daily, or more frequently) and vbouncer-clean.php (weekly, equal to Bounce limit period) 6. If you are using vB's SMTP email option, make sure to also enable the "-f" option. Change log: - August 12, 2005 v1.3 Update to the cron files to match new changes in vB's cron/tasks. To upgrade, just re-upload the contents of includes/cron. - July 11, 2005 v1.2 Bug fix for some server/PHP setups; resolve aliases for return keys, otherwise some aliases would be considered forged. - July 5, 2005 v1.1 Bug fix in standard report pattern matching - July 4, 2005 v1.0 Added encrypted header for authentication (suggested by Paul M). - July 3, 2005 v0.9.1 fixed a bug preventing IMAP/POP log collection. - July 2, 2005 v0.9 added IMAP/POP option and custom filters file vbouncer.ini - June 27, 2005 v0.5 Added custom header setting option, for re-written headers. - June 26, 2005 v0.4 Found a way to make it work as a plugin, without code edits (thanks to Paul M) - June 26, 2005 v0.3 No changes, just removed the plugin - June 25, 2005 v0.2 Added NDR/Reply code errors to stats, and option to act upon 5.0.0/550 (user unknown) - June 21, 2005: v 0.1 Initial release. Marked beta, but it's working fine on PostFix and SendMail. Need to hear from those who tried on QMail and Exim Show Your Support

The header you showed will not be picked up by vBouncer since it's not RFC compliant, I think. Exim maybe re-writing them. If AOL, Comcast and hotmail result are in the same format, then Exim on your server might be intefering, since those ISP's do send (most of the time) RFC compliant non-delivery. |

Sure - I'll PM you the results.

vBouncer 0.4 now works as a plugin, without code changes. (Thanks to Paul M)
To upgrade from 0.2 or 0.3, simply delete the old plugin and replace with the new one. |

Thanks tamarian!
I am also on cPanel/Exim. Will be upgrading my server to a new box this month, but I anticipate that will be the same as I believe this is core cPanel behaviour on mail handling -- I don't think it is an option? I will gladly help with testing as well. Just let me know what you would like done. |

Well, with a few bits of suitably placed sticky tape - I have a working system on cpanel / exim. I think tamarian will be producing an update later.

A better solution, IMHO, is to use the dot-forward file method (a feature available on all these mail packages, including Exim) to directly pipe the file to another in the public_html area. I'm still looking for the correct format, but if anyone knows, please share. Another problem with Exim, is re-writing the headers for the bounced files, which will be missed by the current log collector. I'll release an updated version to capture those. Does the CPanel/Exim show an option to forward to a file? |

The PHP restriction you speak of, would it happen to be open_basedir?
I use this extensivly across my enviroment. All you have to do is add a single path to the directory block of the vBouncer files that allows php to access the path to the spool file. If it isnt open_basedir, im not sure |

I suspect CPanel might be chrooting the seperate systems, but I'm not sure, since I don't use it. But I can try to override the php.ini to see if that helps. |

I do my modifications for each virtual site on my system in httpd.conf (using php_admin_value so that it cant be overridden by .htaccess). Something like the following will allow PHP scripts to access /www/sitename, /tmp and /var/spool/mail (and outside of these paths will result in an error): Code:
<Directory /www/sitename> php_admin_value open_basedir "/www/sitename:/tmp:/var/spool/mail/" </Directory> Oh, and this wont help you if you're in a chroot enviroment |
