So if we set fom_is_list to No and dmarc_moderation_action to Munge From, non yahoo/aol emails will go through normally, and yahoo/aol emails will get munged? That's what we want. We're seeing too many side effects from munging them all.

Good, we don't need that. I've been reading the messages here about these options ever since yahoo made the change that prompted their creation, but without understanding properly because we were stuck on 2.1.15.

Yes. I somehow got the idea there was an addional "safety net" that would give moderators a last chance to choose to munge or wrap at approval time. Like if dmarc_moderation_action had a Hold option.

Very few of our yahoo/aol members ever post. Lots of those who did have already changed to gmail when we asked, but a couple remain. If they still won't change then they'll have to put up with this.

I've discovered another side effect of munging and iOS Mail, which I'll mention in another thread.

Thanks for your help,
