Latest round of SpamAssassin rules I'm using, if anyone is interested.
The highlights here are just a couple of things:
- A few new sources which come with new rules
- Slight scoring tweaks on just a few rules
Of course, as they say... YMMV.

Just wanted to share to maybe inspire others if they think they'd benefit from some extra bit of flair in their Dashboard.
That's not Cloudron's fault at all, I'm just very surprised this issue wasn't taken more seriously by the upstream developers. Guess I'll have to stick to Matomo for a while longer.
Thanks for the insight, I'll definitely consider that going forward! I don't currently advertise as GDPR-compliant because my customers and I are all located in Canada where the GDPR doesn't exist (and they only offer their services in Canada too currently), but I try to follow the general philosophies / intentions of it such as respecting do-not-track cookies, logging least personal info as possible, able to delete the data upon request, etc. This is good info to have though if that all changes for my customers or my own offerings where I need to then pay more attention to GDPR.
