I don't think it's a DNS server problem.  I suspect it's due to differences
in the mail software in use at your site versus hotmail/yahoo.  Since the
misbehavior only appears when performing ANY queries, I suspect your mail
server is using this type of query, whereas hotmail's server uses MX
queries.

I don't know if or how you can configure your mail server to use MX queries
instead of ANY queries.
