Thanks - thought it was right but wasn't sure. Found another jeos errata. The ss_update.sh script uses rsync which you have to apt-get for jeos. Also the clam_pid line in the script reads:
when it is actually at:
(final directory in the path is clamav not clamd)
I didn't see any instructions to change it but may have missed it. So far your how-to has worked great. The final test will be if I manage to actually filter spam. We've been using a fairly simple Spamassassin setup but I'm hoping to get better results with your config.
