balka.com is the lowest available priority MX for balka.com even
though it doesn't accept mail for it.
You're trying to relay mail to balka.com, so Postfix basically sends
mail to itself in a loop, because it is not configured to accept it
and so tries to relay based on the MX records.
If the domain is hosted on another machine (say on an internal
network) you probably need to use transport_maps.
Why is your server the lowest priority MX for balka.com, if you're
not trying to send mail to it?
