Can you be born radicalized ?

Born & raised in a communist dictatorship country, were even a joke could make you disappear (aka torture/dead) followed by a bloody revolution as a teenager followed by a simulacrum of democracy combined with very high corruption in form of an idiocracy.

I did not need any vendor lock-in or software lock-in to open my eyes… I just don’t trust by default :)

You can find the answer in the documentation of Nextcloud + various apps.

We use Nextcloud for this.

Hello.

I run multiple email servers for different companies on multiple servers in different locations all onprem. Some are CTX containers on Proxmox some are just older physical servers.

Do not even try to run it on VPS or on any low reputation IP’s or internet domains.

Use a different internet domain (not subdomain) and IP for your marketing/newsletter/e.t.c. or such that are susceptible for blacklisting, so your business email still get trough.
