This is not likely to be a bug. It is definitely not a bug in how RDNS_NONE is
scored.

It is almost certainly a problem with local configuration of the critical
trusted_networks and internal_networks parameters. It is impossible to
determine that without knowing the IP which has been removed from the example.

As this is a configuration error, not a bug, it is an issued better addressed
to the SpamAssassin Users mailing list, where other users can advise on how
they configure systems that might be similar to yours.

For future reference please mung (modify for privacy) as little as possible and
always leave a valid email. SA wont understand xx.xx.xx.xx as an email address
and anyone wanting to test the headers above will have to edit them first.
There is no point in munging the server addresses of email service providers.

If I'm following this correctly, you sent a test email from seznam.cz webmail
to your mail server, which then passed it though SA and redirected it back to
seznam.cz. In that case the redirection is not relevant. The problem is here:

Received: from unknown (HELO mxb2.seznam.cz) (xx.xx.xx.xx) by
server.myserver.eu ...

Your MTA is saying that the rDNS for the seznam.cz outgoing server is unknown,
and this will cause RDNS_NONE.

Most likely you just need to turn-on rDNS look-ups in your MTA, SA needs the
MTA to do that look-up, or everything gets RDNS_NONE.

It's impossible to say whether the seznam server has bad rDNS as you munged the
IP address.

Received: from unknown (HELO mxb1.seznam.cz) (77.75.78.89)

I putted IP address at trusted_network as param and restarted SA.
And still have RDNS_NONE.

I already told you the problem is the 'unknown' in the received header.

Either your MTA is not configured to do rDNS look-ups or there's a DNS problem
somewhere. This is nothing to do with SpamAssassin. Changing trusted_networks
would have, at best, just hidden the problem.
