well, i think that answers my questions:
Do not use PBL in filters that do any ‘deep parsing’ of
Received headers, or for other than checking IP addresses that hand off to
your mailservers."
according to that, i should check only the first received from header

I would not be surprised if the "failures" you got on those addresses were
actually from the Policy Block List, and thus not necessarily spammers. You
might want to further restrict what you consider spammers by testing for a
range of values (specified on that http://www.spamhaus.org/zen/index.lasso
page highlighted in the previous note).
Quote from that page: "Caution: Because the PBL lists normal customer IP
space, do not use PBL on smarthosts or SMTP AUTH outbound servers for your
own customers (or you risk blocking your own customers if their dynamic IPs
are in the PBL). Do not use PBL in filters that do any ‘deep parsing’ of
Received headers, or for other than checking IP addresses that hand off to
your mailservers."
