Because the dynamic address you're relaying from is on the Spamhaus list, and the static address is not? You should also not have *both* zen.spamhaus.org AND sbl-xbl.spamhaus.org - the Zen list includes sbl-xbl. You can query the zen list for your dynamic host by running "dig rev.erse.IP.addr.zen.spamhaus.org" and seeing if there are any entries. Show some logs for your rejected emails, if that doesn't seem to be the problem.
