"Der Name oder der Dienst ist nicht bekannt" => 
"The name or service is not known". :)

This looks like a name service failure.  Are you running a name server?

See for example

https://serverfault.com/questions/129556/how-do-i-fix-getaddrinfo-localhost-name-or-service-not-found-for-telnet-serve

It looks like rspamd is asking for the IP address for 'localhost' and
it isn't getting a reply that it understands.  The name resolution
issue is most probably on the host which is running rspamd, it would
be unusual to ask a remote nameserver for the address of localhost.

The name 'localhost' would normally resolve to the address 127.0.0.1
(for IPv4) or the address ::1 (for IPv6).

You should be able to get a response from the command 'ping localhost'
similar to this:

8<----------------------------------------------------------------------
$ ping -4 localhost
PING  (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.110 ms
64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.362 ms
64 bytes from localhost (127.0.0.1): icmp_seq=3 ttl=64 time=0.263 ms
...
...
8<----------------------------------------------------------------------

The above ping on my desktop used IPv4, because I added '-4', otherwise
I would see

8<----------------------------------------------------------------------
$ ping localhost
PING localhost(localhost (::1)) 56 data bytes
64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.116 ms
64 bytes from localhost (::1): icmp_seq=2 ttl=64 time=0.129 ms
64 bytes from localhost (::1): icmp_seq=3 ttl=64 time=0.102 ms
...
...
8<----------------------------------------------------------------------

but it depends on how your system is set up whether it default to IPv6
or IPv4.  CTRL-C quits ping.

Usually you will have a file

/etc/nsswitch.conf

see for example

https://en.wikipedia.org/wiki/Name_Service_Switch?wprov=srpw1_0

which determines how searches for names are performed - names like
'localhost' are often resolved by reading the local file

/etc/hosts

see for example

https://en.wikipedia.org/wiki/Hosts_(file)


Usually there's also a file

/etc/resolv.conf

see for example

https://en.wikipedia.org/wiki/Resolv.conf

which configures parts of the name service.

Check that you have those files and that the contents make some sort
of sense.  They're only small and there's nothing secret so you could
post them here.

See for example

https://debian-handbook.info/browse/stable/sect.hostname-name-service.html

for more information.  Different distributions have different ways of
setting up name resolution so to be specific we will need to know more
about your system.
