My guess is you're referring to the XBL lookup and are likely on the CBL which reacts very quickly. http://www.spamhaus.org/ZEN/ which is the Spamhaus DNSBL that I use.
It is extremely rare to see legit mail blocked by that list and there are likely technical problems with the sender leading to them getting listed by the CBL.
My guess would be that these spam would be blocked by the CBL or NJABL proxy list.
