Agree. "Discard" and "silently discard" mean the same thing, in my

Maybe in an attempt to be slightly over-specific.


I do not recall seeing a dictionary or technical definition of "discard"
that says anything at all about whether the discarder says anything at all.

Taken on its own and without further technical specifications 'discard' does
not direct, imply or request that the action be silent or noisy, and if
noisy who gets to hear it.

I'm perfectly fine with being more explicit, but I do think there's an
implication of silent by the use of the word discard in the context of
email delivery. If it's not delivered, it's either bounced back --
rejected, with a DSN, or discarded. The 99.9999% example of this is
Hotmail, and their discarding is silent. I would also suggest that a
noisy discard, perhaps "discard + a status notification," (is there
any other kind there could be?) is already covered by the existing
case of a DSN/bounce.

So, by my own experience, my only experience with discarding, it has
always been and only been silent. Like I said, I'm fine with being
more explicit, but keep in mind that I sure that I am not the
exception as far as my understanding of what discard means in the
context of email delivery.
