While configuring the MM 2.1 DMARC mitigation code for use in Courier- MTA I note that the return from _DMARCProhibited(..) for a detected policy of "p=none" is True, just as it is for "p=quarantine" and "p=reject". Why is this? I would assume that if this code is reached, and p=none, that no From munging would be required.
I think the code you're looking at is conditional on dmarc_none_moderation_action being True which is neither a default nor a recommended setting. It was added (reluctantly) in response to <https://bugs.launchpad.net/mailman/+bug/1539384> and probably should not have been. It is not in Mailman 3.
If you have time and interest, read the bug report (and all 11 comments).
