Oh so then this is completely something configured wrong on their end using Microsoft Exchange, right? I just sent email from the same IP to my personal and friends Postfix mail servers who both use RBL checks to zen.spamhaus.org and they passed through fine. Can I ask what the normal procedure is for mail? If the latter IP is listed on a PBL but the last received IP is not, does it then allow? Does Postfix only look at the the most recent received client IP for RBL checks and thats all?
