Hello. Exim is broken. What could be the problem?

failed to open /etc/exim4/domains/ for directory search: Permission denied (euid=104 egid=112)

There are symlinks to user files here. I don’t understand what the problem is. Nobody did anything.

I don’t even know how to solve the problem. Can you advise something?

For some reason the permissions on the domains folder changed from 755 to 771
