The STRESS_README was written before postfix supported 521 as a hangup

I am somewhat hesitant to recommend using 521 as your "standard" RBL
reject code since the RFCs don't specifically mention 521/disconnect
as a valid code (421/disconnect is mentioned as a special case). On
the other hand, clients "MUST" interpret any 5xx code as a permanent
reject. This hasn't been widely tested and there's just enough wiggle
room here that it's possible some clients will behave badly. But it's
probably fine.
Thanks for the info. I think I'm going to go ahead with it since only
about 5% of my mail hits the RBL anyway.
in rbl_relay_maps does each possible IP have to have a separate block is
there a way to 'wild card' them all into one declaration? and are the
line feeds shown in the example significant?
something like:
zen.spamhaus.org=127.0.0.* 521 4.7.1 Service unavailable;
$rbl_class [$rbl_what] blocked using
$rbl_domain${rbl_reason?; $rbl_reason}
(obviously that's not going to be the syntax, but is there a way to
combine 4-11 of even 2-11 into one declaration?)
maps_rbl_reject_code = 521
