You mean starting from the email domain, looking up MX record(s) and getting one or more A record(s), then looking up those A records to get one or more IP(s) - finally looking up IP(s) in a local blacklist (or in DNSRBLs - having reversed the ordering of the octets!). And at each stage, possibly getting silly or anomalous answers out of the DNS... > I suspect it would be fiddly. Quite so! and it's something which exim has to do internally anyway - at least as far as looking up the A records to get IPs - which is why it seemed so genial to tag along with that ignore_target-Hosts mechanism. thanks. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
