Yes, I noticed this, too.  (Might have been the delay while callout check
of the delivering IP was underway.)

I haven't looked up rfc-clueless.org's delisting procedure.  Some DNSBLs
ask you to send mail somewhere making the request.  If that's the case,
then I suppose you could send the relevent telnet transcript, showing
RFC compliance.

People running DNSBLs tend to be cranky and cynical, or become that way
if they aren't already.  They're also overly busy and wary of
comminication with complaining sysadmins as a time sink.  However, when
all is said and done, they do try to work with sysadmins who _are_
playing by the rules.
