Emails with multiple recipients only showing up to one recipient

[mpalmer (Matt Palmer)]

I’m pretty sure we only post to the group indicated by the first valid-looking e-mail address we find. Arguably, for caegories at least, this is correct behaviour, because Discourse doesn’t have the concept of “a single message which exists in multiple categories”, and while it might be annoying to have your carefully crafted missive only show up in one of the places you expect it to, splitting the conversation on one topic into two places seems like cutting off your nose to spite your face. PMing multiple groups could be done, but it’s a very niche corner case that I expect just wasn’t considered during feature development. “PR welcome”, I suspect.
