The system you're sending your e-mail *to* has upgraded their Sendmail to the
version which supports various anti-spam features, including verifying that
the sender domain of all incoming messages must be resolvable via DNS.

If the message you quote is the exact error and not some symbolically
cleaned version, then I think you're generating some corrupt message headers....
