This is a sendmail configuration problem, not a DNS problem (the error
message was written by someone who assumed that administrators know how to
configure sendmail, so an inconsistency was probably a problem with the
DNS, but this assumption is almost always wrong).

The solution is in the FAQ at www.sendmail.org.
