I was under the impression that I didn't need to accept inbound
connections for TCP DNS lookups.  I guess I do - you learn something
new every day...

Cool, I can do:

(dig-invoke "244.224.91.80.bl.spamcop.net")
[switch to the *dig output* buffer]
check if (dig-extract-rr "244.224.91.80.bl.spamcop.net") is nil

There doesn't seem to be a way to do all of these in one shot in
dig.el; should I write the corresponding code in spam.el or should
dig.el be extended to have a dig-dns-query function analogous to
dns-query in dns.el?
