In debug mode it turned out that dovecot connects to smtpd service as ... "local". Not as locahost, not as 127.0.0.1, not even as real hostname of the server. "local" was not in my list of servers allowed to send any mail. After adding this entry to the list everything works as expected. Big thanks for help!
