It's defined in the RFC as:

"Retries continue until the message is transmitted or the sender gives
   up; the give-up time generally needs to be at least 4-5 days"

See: https://www.ietf.org/rfc/rfc2821.txt

Of course that's an RFC, so while *most* mail servers might work that way there's no guarantee that they all will 

Regards

Michele

It used to be the standard practice was that mail servers would continue trying to deliver for four days.

I¹ll also see if we are tracking/counting this stat.  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.

That's a good question Kathy,
I'll see if I can dig some stats up from our systems.

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
