Norbert, There are DNS block lists out there that allow you to look up a domain to see if it is listed, in just the same way you'd look up an ip address in a RBL.
Something like.... If the RBL was rbl.tld.cc And the domain to look up was spammer.com Then... spammer.com.rbl.tld.cc If it returned 127.0.0.2 (or 127.0.0.1, etc) then it would trigger xmail to block the email. So your monster file would need to be massaged into a Bind zone file, like so... $ORIGIN rbl.tld.cc. $TTL 1D .......... spammer.com PTR 127.0.0.1 Obviously you'd need to insert the SOA/NS records at "........." and any other tweaks you like. Then once you've created the zone file, restart your named. Then in xmail's server.tab - CustMapsList, list your RBL first. (obviously you'd need your resolv.conf to point to your named otherwise you'd need to delegate and make public your RBL.) I have a local named running as a cache anyway, so hosting a zone is an easy step after that. *AND* for all you (me included) windows users, you can get BIND for W32 - so there is no excuse. Davide's comment of using DNS as an efficient lookup tool is very accurate and I'd recommend any list of spammers etc that you have should be maintained as an RBL. Sequential reading of files is just way too slow. There are even RBL programs out there for your local server. One thing they offer is an RBL cache. So xmail queries your own RBL, and it queries any number of RBLS for you and caches the result. This saves in bandwidth too. (Just Google for them.)

The easiest way is probably to have a script that periodically generates a new zone file, feeds it to bind and restart it. - Davide - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
