Let me try again also! I presume your lookup is actually against
key.zen.dq.spamhaus.org. That's what I said was right. Hereafter,
"key" will be substituted for the actual key.

And here you are talking about spamhaus.net. Which is your lookup
against, key.zen.dq.spamhaus.org or key.zen.dq.spamhaus.net? Do note
that "net" is not "org".

Assuming that you DID mean key.zen.dq.spamhaus.org, your
postscreen_dnsbl_reply_map lookup of key.zen.dq.spamhaus.net would
never match, because as we have seen, "net" is not "org". :)

If "net" was right, your munging was wrong.
