[Gnso-ppsai-pdp-wg] Question

[Kathy Kleiman]

Hi Steve and Alex,
Good discussion today - much appreciated. Quick note: I can certainly 
understand the desire to know if an email went through. Quick question: 
do you have any idea how many "bouncebacks" we are talking about?  In 
today's environment, with the current forwarding work by proxy/privacy 
providers, do you have any idea how many messages are undeliverable vs. 
how many may be received but not responded to?  I know each messages is 
important, but are we talking about a high percentage or a very low 
percentage?

Tx,
Kathy
