Set of procmail recipes which handle known/suspected spam

The Spam Bouncer is a set of procmail recipes, or instructions, which search the headers and text of your incoming email to see if it meets one or more of several categories known addresses, rogue ISPs, bulk mail software etc etc.

The Spam Bouncer sorts suspected spam into two categories – mail from known spam sources which is definitely spam, and other mail which is probably spam, but might also be legitimate. It then tags this email with appropriate headers giving the spam classification, and responds according to the parameters you have set.


SpamBNC is a robust FreeBSD port developed initially as an anti-spam solution for Internet Relay Chat IRC networks. However, over time, it has evolved into a favored internet communication tool, bringing together multiple communication protocols and offering a wide range of functionalities that go well beyond spam protection. This guide will expound on the various benefits of SpamBNC and provide a tutorial on how to install and configure it in a FreeBSD system.

Why Choose SpamBNC?

Before we delve into the ins and outs, let’s take a look at why you should consider equipping your FreeBSD system with this versatile tool.

Installing SpamBNC in FreeBSD

Now that we know why SpamBNC is a worthwhile addition to FreeBSD, let’s look at the installation process.

The easiest way to install the SpamBNC port in FreeBSD is to use the pkg package management tool. If you don’t have it installed yet, you can do that with the help of the [pkg package manager port]https//freebsdsoftware.org/ports-mgmt/pkg.html.

pkg update
pkg install spambnc

These commands will update your package repository information and then install the SpamBNC port.

Configuring SpamBNC in FreeBSD

After installation, you’ll need to configure SpamBNC to suit your individual needs. The configuration file for this port is usually located at /usr/local/etc/spambnc/spambnc.conf.

You can edit this file using your preferred text editor. If you are not sure which editor to use, try out the [nano editor]https//freebsdsoftware.org/editors/nano.html - a simple and user-friendly option.

Here’s an example of how to configure SpamBNC
