Sorry, my message contained a spam domain!

Hello!

I run an unbound + rbldnsd combo to serve my RBL
https://github.com/szepeviktor/debian-server-tools/blob/master/mail/spammer.dnsbl/spammer.dnsbl.zone
and do resolving for Spamassassin running on several other servers.

Is there a way to server A and TXT records for my RBL with unbound only?
An example:

-- example redacted --

I could convert this rbldnsd format to any other format if necessary.

Thank you!

Hi Victor,

Unbound can synthesize part of a domain or the whole domain. It is possible to manipulate a domain as needed for block lists, redirection, or supplemental data. Each "local-data:" or "local-data-ptr:" statement is used for an RR before recursive searching. Any typical RR can be put in "local-data" including TXT. For extreme measures, "local-zone:" type "static" can be used to mask out an entire domain (only serves local-data:). The "auth-zone:" clause with URL only zone file fetching might also work, but I have not spent much time working with this new feature.

Hope that helps,
Eric
