The mailman instance running for mozilla.org lists (and any other mailman instances) still doesn't handle e-mail appropriately when coming from domains that utilize DMARC, even with the work done in bug 995330.

Looks like mail.mozilla.org is running Mailman 2.1.18. If this is correct, then need to set the dmarc_moderation_action to "Munge From" (or some other option that will cause mails to not fail DMARC checks.

DMARC report statistics for reedloden.com

I just enabled DMARC on reedloden.com with p=none, and here's a day or two of reports...
Lowering so oncall doesn't get paged ?

Yes we are runnig 2.1.18 and the dmarc_moderation_action option is a per list option so users can set this on their own.

The setting should be made globally. There's no reason for this to be a per-list decision.

The users are the one that decide this, I will not enforce this globally the option is there for the users ultimately and they can make the change on their own

limed: I'm not sure all list operators even know about this. I understand it fairly well and I didn't know it was unset on a list I manage until someone complained. Why are you making "make email work" a non-default option which has to be enabled? That seems wrong...
