After the domain went back to normal, I continued to have a problem with RDJ. It still reported lint errors.
The problem was that the RulesDuJour directory had become corrupted with the temporary page that had been downloaded during the outage. The fix was to simply delete the contents of the directory and try again. rm /etc/mail/spamassassin/RulesDuJour/* ./rules_du_jour Just FYI if anyone else is having the same problem. -- Bowie
