[Mimedefang] Verifying sendmail aliases securely

[Kenneth Porter]

I don't want to expose the verification and expansion SMTP commands to the 
outside world but it's useful to expose them to the internal local 
interface for debugging. Should I do that from sendmail with some kind of 
sendmail.mc command (does such a thing exist?) or is it possible to do that 
from within MD?

Or am I better off doing this somehow from the sendmail command line?
