So it's saying that b-b.sk is an unrouteable mail domain...

As seen from here, the domain b-b.sk looks-up as

10 mta-in.stonline.sk
30 postar.telecom.sk

Both of these correspond to one A record

host mta-in.stonline.sk
mta-in.stonline.sk has address 213.81.152.19

host postar.telecom.sk
postar.telecom.sk has address 195.146.132.55

Both of those addresses currently respond to an SMTP call from here.

I could well believe the hon. O.P's claim that the effect is sporadic.

I take it that exim is handling this as a fatal error and returning
5xx, rather than as a retryable error and returning 4xx ? That's
obviously a bit awkward. You might want to add an exceptions list to
your "verify = sender" stanza to work around this while the problem is
investigated.
