Hello,

I wanted to know if there is in fact a norm which manages the Mailing List
tools in general.

I explain my ask. In fact, i use an old sympa version. This one to know if 
user
is authorized to write to a list makes a test on the context sender value 
which
has been valued differently from the original sender.

So if a user send a mail he would not received the  DSN for vacancy or
Overquota.

Is there a good behaviour? For example in outlook if the 1000 suscribers are
not in office you'll receive 1000 DSN...

Is there a document which normalizes the behaviour of a mailling list tools

Best Regards,

Vincent
