Unfortunately, ADSP did not define what was meant by "discardable".

signing key, or any other reason, the domain
encourages the recipient(s) to discard it.
Keeping in mind that senders cannot force receivers to do anything,

given the recent discussions, it seems to me that people want to have a
definition of what 'discard' means in the context as described above. As
a non-native English speaker (or what's the right term?) I suppose (but
am not sure) the word 'discard' can have multiple meanings (apart from
'To throw away'). Otherwise 'silently discard' would be a pleonasm,
I suggest to put the subject 'discard and discardable' on the to-do list
for a next revision of ADSP. If my analysis (that the word 'discard'
means different things to different people) is correct, then there's
still some discussion to go. After all, throwing away mail silently is
contradictory to the original SMTP model (mail is delivered or a NDN
comes back) and can have negative impact on the reliability of the
e-mail system, as perceived by users of e-mail.
