Rules in Notes 6.5 do not work

To fight spam I hoped to use Rules. So I did in Notes 5. I noticed their weird behaviour (sometimes not saved properly, or reporting errors like ‘index out of bounds’, or ‘error in cell calculation’, not detecting spam-characteristic strings like ‘viagra’ in many multipart emails. However after I was upgraded to Notes 6.5 things got worse. New rules seem not to work correctly - they do not detect trivial strigs in simple emails sent to myself. Or work sometimes, whereas old problems remained. Interestingly, even if I delete a new rule, it still acts!

(Rules were like: “IF BODY DOESN’T CONTAIN myname SEND TO SPAM”. To solve this, I deleted the folder to which it sends spam.)

Our Help deks “knows” a solution: delte ALL rules and try to create new ones - but I do not want to loose old rules of version 5 that work.

Is there a way to save them somewhere and then to import them into new database?

Do you maybe know source of some useful info (not saying that IBM did a wonderful job in fighting spam in Notes 6) on this kind of problems? Anybody from IBM/Lotus who reads this forum - PLEASE help!

Thanks!
