Setup Postfix with postscreen RBL weighting. This IP is on a number of
Search the SpamAssassin mailing list archives for senderscore.org and you
should find some Postfix postscreen details along with extra rules to add
to SA for RCVD_IN_SENDERSCORE.
That message would have been bounced by Postfix but if it made it to SA,
then it would have scored a 29.2 in my MailScanner.
