pulling my hair out...
bayes: bayes db version 0 is not able to be used, aborting! at /usr/lib/perl5/vendor_perl/5.8.0/Mail/SpamAssassin/BayesStore/DBM.pm line 160.
This is exactly the same situation I was complaining about earlier today.
It all comes down to something happening with the autolearn or something in the running Spamassassin causes the bayes db to become version 0 from version 3, and stop working.
If anyone comes across a solution, we'll both be appreciative.
