If the best option was chosen, as @watchmanmonitor points out there would likely be a need to change the owner of a post if the wrong email is used. One concern I have is that change ownership currently is an admin only feature, moderators can’t do it. Just something to keep in mind.
I’m also interested in that. We’ve been using mail-in to a group inbox and it was mostly awesome, but a few times, we’ve missed some important mail because Discourse rejected it.
I’d love to have a way to ensure that every mail is received, even if it’s just to the “holding pen”.
I agree with @fefrei, even spam. There’s a reason all modern email clients have a spam folder/trap, and not a black hole. Algorithms aren’t perfect. Same reason Akismet requests a staff review, and doesn’t just delete the message. If an email can’t automatically be added to a topic for any reason, staff should be able to see both why, and resolve the issue so it can be posted without another email being sent.
No argument there. The user in the original example did get a valid reply, I was merely expanding on @fefrei’s post and your question (“Even spam…”).
To @fefrei’s earlier point - “We’ve been using mail-in to a group inbox and it was mostly awesome, but a few times, we’ve missed some important mail because Discourse rejected it.” This has been an issue for us (my site, not Stonehearth) because to the user they’re sending an email to a support email. They’ve been very confused (even when the reply from Discourse is perfectly clear) why their email was refused - they just expect it to be received, regardless of whether they have 20 characters in the body, 15 characters in the subject, etc.
