Thank you for your response, my whole drive uses ZFS and I have a ZFS
volume for my whole /home/*. My Maildir in itself is just a folder in my
~, and do not have anything special.

I have encountered this behaviour also on my previous setup (migrated
last week-end from Archlinux to NixOS), and this one was using ext4, so
it does not seems to be ZFS related.

Regards,
