The domain is resolvable. It's a local domain, that's why the server
rejects the message. It can see that the username doesn't exist and
dumps the connection right away. Here's an example, the mail never gets
sent. "woohoo.com" is the local domain:

Every little bit helps.
so I want to shut off the "MAIL FROM" test in
sendmail. I have a client who sends out email alerts using the server
and uses a random invalid return address for each alert. Sendmail is
rejecting the messages based on the From field.
Have you tried:
FEATURE(`accept_unresolvable_domains')
