Do you use by any chance LXC or some other sort? If yes you may switch to KVM something like that

[SteffenBarthel]

I use XEN. Do I still need to switch to KVM for this to work?

[chriscroome]

I've been running Mailcow on Xen on Debian Buster and Bullseye for a long time and haven't have any issues related to Xen as far as I'm aware.
