Let me clarify a little. The DNSBL checks made by the antispam module would first try to use the internal (local) port 53 rather than using internal ports above 1024. This caused a problem with Microsofts DNS server since it shares port 53 and IMail could use it as well as the DNS server. What ended up happening was IMail would sometimes not get the response from the DNS server. What has been changed is that IMail will no longer try to use internal port 53, but it will still connect to external port 53 when doing DNSBL queries.
