[Gnso-ppsai-pdp-wg] Question

[Alex_Deacon at mpaa.org]

Thats right.  

We are getting into the weeds here but when the “sender” (SMTP server in the context Michele provided below) finally gives up it will send a hard bounce back to the address in From: or Reply-To: header. 

When this happens the service has X days (2 days based on the recent thread) to process the message and notify the original sender of the bounce.

Another helpful data point might be how many ³bounces² are later resolved, meaning the delivery failure was a temporary situation that was later corrected.  This could be important if a relay obligation were framed in terms of ³unsuccessful delivery after X attempts or within Y business days² or something similar.
