Good. The domain isn't local, it is not listed in the transport
map, and therefore Postfix gives the mail to the SMTP client.

Right. The Postfix SMTP client looks up the MX record for balka.com:
balka.com. 1D IN MX 10 smtp.balka.com.
and the A record for smtp.balka.com.
smtp.balka.com. 23h58m9s IN A 209.15.32.137
Postfix reports "warning: mailer loop: best MX host for balka.com
is local" when the IP address matches $inet_interfaces or
$proxy_interfaces.
So either your DNS is screwed or your inet_interfaces or proxy_interfaces
settings are.
