I'm no sendmail genius, but I know this shouldn't be happening. No
changes? Really?

As someone else suggested, check relay-domains. Also check virtusertable
to make sure you have no @domain.com entries. Anything like this would
be a config change. If you haven't made any config changes then check
anyway.

Also, there were a couple of sendmail security advisories lately. Make
sure you're up to date on those.
