Thx for Chris J. for explaining why rblsmtpd stopped working with
relays.mail-abuse.org.
Such emergencies I think just really show the necessity to simplify
"rbl" lookups. Namely, I think rblsmtpd/rbldns should work in such a
way that any mail administrator should be able to set up a local
mirror of mail-abuse.org. This means, there should not be a need to
have a domain delegated to the rbldns server.
So what if there was a flag `R" to rblsmtpd so that
rblsmtpd -R a.b.c
would mean in essence "check the connecting IP at the server a.b.c running
rbldns".
BTWY, I know many people are attached to using DNS for rbl lookups,
but would not it be relatively simple to implement a server software
using tcpserver that would just lookup an IP number in a .cdb database
of IP numbers, and send an appropriate response? A client might be
similarly simple to implement using tcpclient.
