AFAIR someone posted a few months ago that those lists are empty. Has that 
changed?

Nope.  They are still empty.  I just checked my fresh data feed and
they only have one test record.

About 95% of the rejections/blocked from postscreen show up as blocked

checked by postscreen.


RBL rejections are generally done in order listed.  You list zen first, so 
it is tested first.  If it gets rejected by that RBL, then there is no 
reason to evaluate any further RBLs.


Thus if you see anything being blocked by something other than zen, it 
means it isn't in the zen list, but is listed elsewhere.

 How does post screen decide which RBL to list in the log? 

It blames the DNSBL with the largest weight.

The initial postscreen implementation blamed the DNSBL that replied
first. That was considered misleading, especially when that DNSBL
contributed very little to the total score.

 RBL rejections are generally done in order listed.  You list zen first, so 

postscreen queries DNS[BW]Ls in parallel. The blame is based on the
DNSBL weight, as described in my other follow-up.

Thank you. In the case of a tie does it list both or the first one to respond 
or the the first one listed?

Ah, sorry, I should have noticed postscreen vs postfix. ;)

I make no promise of what happens. When two equal-weight DNSBLs
produce the same response, then it should not matter which one
responds first or last.
