Re: Advice sought for mailets

Hello Matt,

1. is easy: just put it at the beginning of the transport protocol.

2. is slightly more challenging:
  a. For RemoteDelivery use onSuccess property to pass a callback upon 
success (need another processor)
  b. For LocalDelivery pass property consume to false and handle success 
afterward il a processor called "local-delivery" is a common practice.

3. is slightly harder. You would need to plug your logic in the various 
places handling all kind of error: error processor, rrt-error processor, 
bounces processor, local-address-error, relay-denied ...

Hope this helps.

Best regards,

Benoit
