[Mimedefang] Odd "error state"

I'm looking for any insight on what caused this odd event in the log. 
Below, these are the only two lines for sendmail process 12377 and the only 
one line for queue id t9SHqutp012377.

The second line shows a recipient address (changed here) that really was 
User unknown, but no from= line is logged. I don't know how to duplicate 
that. As expected I cannot send RCPT before MAIL at port 25.

And in the same second sendmail said Milter went to an error state. I went 
back 5 minutes and see no error messages logged by Mimedefang itself, so I 
have nothing to track that down with.

Milter (mimedefang): to error state
