Since others answered your error message, I'll answer the first question:
smtpd_restriction_classes = class_barracuda
class_barracuda = reject_rbl_client b.barracudacentral.org
smtpd_recipient_restrictions = <..>
class_barracuda,
See http://barracudacentral.org/rbl
This is a very effective filter run by a commercial entity (ie, Barracuda,
the people who make and sell spam filtering appliances), so they have a
name and reputation to protect. (Ie, it's not just some pissed off admin
that blocks all of 12.0.0.0/8 because AT&T sucks...)
The only false positives I've seen in the last year or so is because of
fun mail forwards to our support staff who decided to report all their
spam to barracuda and forgot to list our mail server as a trusted relay
to theirs. (The barracuda people were very helpful in this case, offering
a threeway call to their appliance customer to explain the 'trusted relay'
setting and why they should use it if mail was .forwarded to them.)
And, yes, the barracudacentral.org list is free.
