I have been using spamhaus, spamcop, sorbs as the RBL providers for

But some of the customers speak to me about the FP issues caused by RBL.
Do you think the three RBL above are reliable in a practical system?

I use them on many servers.

I just use postscreen which supports scoring and only block when more than one blocklist hits.

For the benefit of those of us following-along with the conversation and hoping to learn 'nuggets' of good-practice, would you mind sharing the settings related to the combination of RBLs and postscreen, please?

Yes slightly OT, but relates to getting the best from postfix!

I have posted it multiple in the past, last time not so long ago and haven't changed it since:

I am posting link to the archive, because I also find searching archives for postscreen_dnsbl_sites as the best way for seeing people's configuration and others' comments about it.

Others also posted their postscreen_dnsbl_sites, but I recommend reading replies on that configuration, because people often discuss it here when something bad happens.
