This is several bugs in qmail. It is making the query in order to canonicalize 
the domain in outgoing email, which it does not need to do according to the 
current SMTP specs. 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.

Qmail is buggy and unmaintained and has been abandoned by its author. Best 
avoided.
