Well the problem is with SA testing the domain name of the sender in the
Receive and Return-path headers. For some reason the DNSBL-MX times out.
 dbg: dns: launching DNS A query for gmail.com in background
 dbg: async: starting: NO_DNS_FOR_FROM, DNSBL-A, dns:A:gmail.com
(timeout 10.0s, min 2.0s)
 dbg: dns: launching DNS MX query for gmail.com in background
 dbg: async: starting: NO_DNS_FOR_FROM, DNSBL-MX,
dns:MX:gmail.com (timeout 10.0s, min 2.0s)
Nothing wrong with MD... great software for which I'm thankful
