Your DNS server is fabricating A records for non-existent hosts. The
real spamhaus would have also returned a TXT record with a URL for
looking up the reason for the block.
Don't use ISP DNS servers that fabricate A records.
I'm not using our ISP's DNS , I'm using OpenDNS, I'm using OpenDNS
since way back it's only now that I'm getting this strange behavior in
my SMTP server.
You need to sign up for an account with OpenDNS, register your
IP address and disable their "Typo Correction" feature.
I'm doing this at a site with poor internet connectivity, and
it works quite well with postfix.
