python3-cyberfusion-rblchecker

Use rblchecker to check whether your outgoing mail IP addresses are listed on RBLs.

The following checkers are supported:

• DNS
• • Every host in the config is checked.
• Microsoft SNDS
• • Not only blacklisted IPs, but also IPs with a 'special' status are returned. See 'IP status' on https://sendersupport.olc.protection.outlook.com/snds/FAQ.aspx

Install

PyPI

Run the following command to install the package from PyPI:

pip3 install rblchecker

Debian

Run the following commands to build a Debian package:

mk-build-deps -i -t 'apt -o Debug::pkgProblemResolver=yes --no-install-recommends -y'
dpkg-buildpackage -us -uc

Configure

Find an example config in config.yml.

Usage

Run all checkers:

rblchecker --config-path=...

Example output:

(DNS) IP address 198.51.100.100 is listed on access.redhawk.org (100.100.51.198.access.redhawk.org -> 127.0.0.0)
(SNDS) IP address 198.51.100.100 is listed on SNDS (reason: 'Junked due to user complaints or other evidence of spamming')

If there's any listings, the command exits with a non-zero RC.
