As the description says, SpamAssassin thinks that the mail was "Received _via_
a relay" found in two blacklists, i.e. directly from 213.158.196.99.

If the above is the ruling of the remote SA, then it seems that the remote
system failed to add a correct Received header line to the mail before
passing it to SA.
