Answer
Don't leave them alone together.  put them in separate spaces.

Front door aggression or inappropriate behaviors is a problem that must be addressed in person by a certified applied animal behaviorist (Ph.D. or DVM.)  Desensitizing this is difficult and the behaviors must be seen firsthand, as well as a temperament evaluation for both dogs and a strong case history regarding other behaviors.  Contact the veterinary college closest to you and ask for a referral.
