Implementing RBL functionality in spamd
Hello,
As spamd is meant to be used a the very front end for receiving mails,
that would be the MX record for a domain, I was thinking that actually
it would be great if spamd could also use RBL as blacklist source. For
example zen.spamhaus.org.
Now in spamd.conf there is the possibility to use exec and I guess
writting a script doing queries to a RBL source would work but maybe it
wouldn't be very effective (forking a shell script which forks a dns
query and so on). So I wanted to suggest maybe implementing a new method
called "dns" or "rbl" where you would just specify one or many RBL
sources to query.
What do you guys out there think of this idea ? Would this work ? Has
someone already tryed something like that and can share his results ?
Regards

Well it's nice that once upon a time it had this feature but doesn't
help much ;-) I was more thinking that implementing a DNS querying
system directly into spamd which can then use any RBL sources directly
(without the need of downloading a list). Would that sound like a good
idea ? I am convinced about it but well have not much experience with C
and then I would somehow need to get a cvs account to be able to commit
and so on. Is someone out there maybe interested in implementing such a
feature ? I am pretty sure a lot of people would be delighted.
Regards
