I agree that if a signing domain publishes discardable then the MLM
should discard it.
If the message is unsigned, right? Otherwise, it should reject it at SMTP
time (actually, that might be done by the MTA rather than the MLM). In fact
the MTA should reject (at SMTP time) rather than discard such messages,
If it's signed, I agree there's little downside to rejecting it. But
since they said it's discardable, there's little advantage to doing so,
A disadvantage is that it requires the SMTP daemon to do a lot of work,
do the whole DKIM validation and ADSP lookup before deciding whether to
reject. You can discard any old time, no need to do it while the TCP
session is open.
