>> I recently migrated SA to a new environment with a clean install. I added the KAM rules and a short rules file of my own. But I'm obviously missing some pretty basic rules that I believe I had in the old environment.
> or Bayes by the look of it. Did you have bayes working on the old setup? Did you port the data files to the new environment? It seems that bayes is not used. Also network checks are not listed in the sample you posted. If you still have access to the old setup, you can copy the .eml and run it on spamassassin manually, with debug active: spamassassin -t <file> 2>debug.log Do the same on the new server and check the differences in the logs.
