Markus,

It's always safer to give negative weights based on reverse DNS instead of the From address. In this case it would look something like this:

REVDNS -5 ENDSWITH .grp.scd.yahoo.com

I also noted that your SPAMDOMAINS_H test got tripped. I would check the configuration there and either adjust or provide a negative weight test to resolve the problem.

Today we've had some FP's comming from a Yahoo mailing list.

Is it a possible solution to give a litle negative weight for mails comming
from @yahoogroups.com or is there any other/bether method to resolve such
false positives? (IP-ranges, Spamdomains...?)

Below the mail header of such a FP:
