Title: Delivery Status Notification support?
Post by: andreas.allacher on February 02, 2016, 09:45:23 pm
Hi,

I think it would be nice in addition to the read receipt notification to support "positive" delivery status notifications which if successful one gets a return receipt nearly immediately.

This is an optional part of SMTP and is not supported by all servers / mail services -- only by a few (most don't).

And I just don't want to deal with "why doesn't this work" or "why is it grayed out in my Gmail account".

Please consider using "read receipt".

OK. I know it isn't supported by many servers but I personally like it more than read receipt because this is transmitted even if the person doesn't send a read receipt.

Acknowledging delivery is a big problem in the world full of SPAM, as it is one of the channels of collecting/confirming existing accounts.
I've heard this many times: "I've just set up a brand new e-mail account john@{server}. I haven't sent any message from it and have not shared this address with anybody, but I started receiving SPAM."

FWIW: I've just set up a new server (that includes e-mail capabilities for the users), and purposely set all defaults to avoid generating or requesting any acknowledgments (delivery, reading, ... ).

Yes, but presumably @andreas.allacher is not a spammer...

This however explains why Gmail does not support DSN (and most other servers / mail services don't either).

He never said so -- I did, "innocent unless proven guilty" :)

But still -- the core issue is that DSN is optional.
