Sendmail has traditionally done an ANY query so that it can get look up the
MX and A records in one query, rather than first doing an MX query and then
an A query if that fails.

I'm not sure if this is a configurable option or it has changed in recent
versions.  I think it's time for you to check www.sendmail.org or post your
questions in comp.mail.sendmail.
