Note: a follow-on release, 1.0.1, includes SSL certificates from Alpine in the Docker image. Please use that instead of 1.0.0.
Lightmeter Control Center 1.0.0 combines recommended fixes for mailserver IP blocks with many usability improvements. This 10th major release unites many features into an all-in-one monitoring system for Postfix mailservers – read the release announcement for details. Check the Roadmap to see what features are coming next.
47 Merge requests and 155 commits went into this release.
Note that Lightmeter is still in early development and intended for small scale deployments. Known issues are documented in README.md. Share your feedback using the dedicated button on every page of the application – we’re listening!
Millions of servers make up the global decentralised email network, most of them use specific criteria to block in-bound mail, and most of those have a unique and custom process for requesting blocks me removed. Lightmeter already detects IP blocking behaviour from the largest hosts like Google and Microsoft, and now it provides advice for getting unblocked too.
Insights which support this feature now include an additional ‘Info’ button which links to relevant advice and instructions in the new Lightmeter Knowledgebase. So far RBL check and Host blocklisting Insights are implemented, with fixes for mailserver IP blocks being offered depending upon the block detected.
New designs for both RBL check and Host blocklisting Insight details have been applied — click “view details” on any such Insight to see the difference. Cleaner grouping of lists and response messages, and automatic linking of included URLs, make starting the unblocking procedure more convenient for those RBLs which include them in their responses.

congrats for the 1.0 version to you. I am courious if lightmeter can be used in an ubuntu linux server (version 18.04 lts and later) with postfix managed by the plesk obsidian software. does lightmeter interfere with plesk or can it be used independently ? any experience ?
Hi Stefan, thank you for testing it 🙂
You can use the docker image or the statically linked binaries from the release page, that should work on any modern Linux distribution, including ubuntu 18.04.
If you want to build it from the source code, please note you’ll need Go 1.15. Ubuntu 18.04 unfortunately officially ships only the 1.10 version.
You can also try installing the latest Go compiler from http://golang.org, which should in principle work on this Ubuntu version, but we have not tested it.
We also haven’t tested the Postfix managed by Plesk Obsidian, so we are unable to say whether it’ll work as expected.
If Plesk Obsidian keeps the logs in the syslog/postfix format in the filesystem, Lightmeter Control Center should work as the only interaction with postfix is through reading its log files.
In case you face issues, please feel free to create a bug report on https://gitlab.com/lightmeter/controlcenter/-/issues or send us a feedback e-mail 🙂
