What are we to do? it looks like the spam filter Thomas installed on openlib.org is creating problems upstream...
I have thought about this a little more on my way home. I think you are probably right, the problem comes from spam being received by nebka, forwarded to snefru, and being declared spam there. But removing the other spam filters is not an option. I used ot get so much spam that it because very difficult to find genuine mail. SA on nebka should be the way to get this sorted. nebka does not appear to be spam listed otherwise, so I think that security has not been compromised. That's an important comfort.
