RBL's & DNS......Roll your own blocklist?

goldfly
Point:  The info I'm gleaning from Spew.org and the like is that they use DNS to propagate and access their blocklists.

Question:  IF I care to block near-spammers like Flowgo.com.  Can I set up my own internal DNS server and list flowgo there while pointing SMTP blocklist at it and POOF!  [:O]ets a boost?

Will this work?  I haven't had the time to expereriment yet, and I know Astaro won't look internally for a DNS server, but what about a blocklist?

    Probably.

    Most RBL's work as DNS servers, and return an IP of 127.0.0.2 for blacklisted mail relays, so you could set up a DNS server yourself and create zones for those, etc.

    It might be easier to do this with procmail or something else on your mailserver though.
