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 worked, qmail could not handle the reply.

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