By default, we re-write the Message-ID of the message that we return to the original sender, exactly to prevent this very thing from happening. You can disable this behavior by going into your Account

Mail stores (namely GMail) will only store the first copy of any email with the same Message-Id. Imagine a scenario where a message is addressed: To: mitch@... CC: main@beta.groups.io I'd

I should also mention that you can toggle the rewriting of the message-ID -- for your own posts -- using the instructions found at

I can confirm that emails originating from the groups.io web interface are provided with a unique groups.io message-id (as they should be), whereas those received via email and forwarded retain their

When an email is sent into group.io, processed, rendered, and re-distributed via groups.io it retains the original Message-Id header as generated by the sender's MUA. I'd expect the re-written to

We can do it, but as you've noticed, we don't currently. We would have to act as an 'email redirector' in that case, something we don't do anywhere else. It is possible to (mostly) do, but would

Hi Mark, my members frequently use database tables across a number of subgroups. I receive notifications that changes have taken place but in order to see them, I have to navigate to the group >

Also, messages can be added. So perhaps that group is not locked, but for some other reason, the "Join This Group" button is broken - er, disabled. Andy

I'm not seeing that. I'm not a member of the group, but https://groups.io/g/4NEC2 appears to be locked (Join button disabled), but no banner on the home page or messages page. I did a full refresh

Hi Andy, That was indeed a bug you discovered, allowing people to join free groups that are over the limit via email. I've fixed that. Also, I've added a banner at the top over every page of a locked

Hi Mark, In doing a test for "Manually following a topic with attachments sends out invalid attachments in the catch-up emails" I discovered another bug or feature, depending on definition. (It is

Hi Mark, It works now but I did discover another problem while testing it, separate report submitted. Cheers, Christos
