[Dovecot] LDA quota rejection

[Eliezer Croitoru]

The basic mail systems do need this option..
We are not talking about plain mail..
Once a message was dropped or was not delivered there is a need to know 
that it was not sent or received.
While some will separate internal mail from external it's their 
preference but once I send an email to a company I would like to know 
that my system and their system is working properly.
In a case that the company do not want to reveal it's computing 
resources to the outer world it's a matter of security and other 
policies rather then basic email policies.

I do remember that in real mail once the recipient box did not got the 
mail it was sent back to the original sender as it was paid for this 
service.
