Not all bounces are backscatter. My servers all deliver DSNs to the sender. My servers don't send backscatter.

So now we're back to my original question. Under what circumstances is it acceptable for an MTA to accept a message and then later return an undeliverable DSN?
I thought previously you said 'none', but now you say your servers do it, so which is it?
My servers do it for mail accepted locally for relay, which is *only* SSL-encrypted and SMTP-AUTH mail. In short, zero chance of bouncing mail to a forged sender.
My server does not accept e-mail from random parties for relay. It either rejects it during the SMTP transaction, or delivers it.
