DSN and NDR

Because of the issue with Apple and killing email messages from mail servers that use DSN. My question is can I disable DSN and still receive NDR?

Thanks

Hi,

As far as I'm aware the NDR is separate from DSN. I personally don't use DSN as I've had issues in the past. I still receive Non-Delivery Reports if delivery has failed e.g. the mailbox no longer exists.

Hope that helps.

Cheers,
Laura Buckley

Yes
NDR is a part of much older part of the SMTP standard set than DSN. I
was getting NDRs long before we even had DSN as an option.

NDRs were specified as a part of return codes way back in RFC 821
(1982) https://tools.ietf.org/html/rfc821#page-34

DSN was introduced 21 years later in RFC3461 (2003)
