I still miss samples for two rules, even if I did had hits according to /var/spool/maillog I did not save them.
I added a sample for the FR_NOTSPAM rule, and I removed the FR_YOURELUCKY rule as I see other forms of the text getting through so it is not efficient. On the other hand, nearly all these messages are caught with RBL rules so I might even remove it completely if I can't find an efficient one.
