And if the postmaster at the receiving end assumes that if this were a brain-dead setting, surely Barracuda wouldn't offer it as an option, now would they?, have them look at the following FAQ page from Spamhaus: http://www.spamhaus.org/faq/answers.lasso?section=Spamhaus%20PBL#185 and, in particular, read the warning about "deep parsing" and why a mail server must *NOT* do deep parsing using Spamhaus's PBL block list (their list of dynamic end-user IP addresses that ought to be sending out their mail via their ISP's mail server rather than trying to talk directly to destinations).
