Mainly my normal phone app. But for a long time it's not sync'd to some google cloud (which would be the default) but a Radicale instance.

I used Nextcloud before but honestly it's a mess to maintain. So much that I would not suggest it without planning to extensively use a lot of the different available addon functions.

Just for file sharing and caldav/carddav I will pick some simple solutions (like Radicale and Syncthing) over Nextcloud any day.

You are talking about reputation management which is not as big a deal as you might think.

Email is a simple system but there are a lot of things at work to prevent (more like reduce) spam.

Some DNS knowledge and some friendly emails to a few abuse @ addresses and a few months of quiet reputation building and you are set.

Add a few weeks of rspamd training and you won't see much spam either.
