It should be making an MX query (not CNAME as it originally did and not ANY as it has done since about 1998) in order to find out if the domain needs to be canonicalized. It also has an undersized DNS packet buffer and cannot cope with truncated replies, so even if ANY queries for microsoft.com worked, qmail could not handle the reply.
