Hi @Spitfireap!

I'm seeing that your contributions are also included in the latest modoboa-rspamd v1.0.0 release.

• https://github.com/modoboa/modoboa-rspamd/releases/tag/1.0.0

We are soon doing the switch from v1 to the v2 series, and have not the best experiences with SpamAssassin, why rspamd comes to mind. Seeing your contributions encourages me to test it out.

Would it be possible to add some documentation, e.g. to the readme, about how to set up rspamd (instead of SpamAssassin + amavis?), and maybe some notes to the modoboa-rspamd repository on how to configure and use it?

I'm interested in checking out your branch here during our upgrade, to give feedback and find quirks, but I would need some instructions on how to work myself there. Thanks in advance for any pointers!

Hi, thanks for your interest. The branch nor modoboa-rspamd is not ready yet for production use eventhough we use it with @tonioo and it does the work (minus some adjustments needed).

We have not developed any migration tool but a backup and restore on a fresh server might do the trick...

As for the documentation, it is not automatically deployed for now but it is nonetheless avaliable here (not quite detailed for now though).

[almereyda]

I will follow the these developments closely. We have no ETA yet for when we will do (1) the switch to the v2 series and (2) to rspamd. Thanks for investing time and effort into this, it is much appreciated.

I'm very interested in testing this branch, esp. due to support for ARC signing in rspamd.

• ARC verification and signing for automated senders modoboa-rspamd#6

Unfortunately we only have a production instance available and a supported upgrade path is a sufficient condition for this integration to work. From my current knowledge, these upgrade instructions should include information about installing and setting up rspamd, as well as removing and uninstalling SpamAssassin and OpenDKIM.

Ideally this is taken care of by the installer.

At this stage of maturity of this PR, does it seem feasible that we set up a testing instance and work towards documenting this upgrade path?
