Strange messages after upgrading Mailman3
Hi all,
I have been getting a few of these messages after my Mailman 3 was upgraded:
"The content of this message was lost. It was probably cross-posted to multiple lists and previously handled on another list."
The messages appear to come from list members and are distributed to the relevant lists, but with nothing of the original contents. They have appeared on different lists with, apparently different senders (unless spoofed). Other messages are going through the system unchanged.
Anyone has any ideas?
Yours,
Allan

To what version did you upgrade? This is most likely https://gitlab.com/mailman/mailman/-/issues/955 which was fixed in Mailman core 3.3.6, but it could be https://gitlab.com/mailman/mailman/-/issues/1027 if the posts are to umbrella lists (lists with other lists as members).

Thank you, Mark, as always.
We upgraded to the latest versions:
Mailman Core Version GNU Mailman 3.3.7 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.9.2 (default, Feb 28, 2021, 17:03:44) [GCC 10.2.1 20210110]
Also, I don't have any umbrella lists.
Yours, Allan

I need more information about this. As far as I know, this can only happen with messages that are cross posted to multiple lists and held for moderator approval on more than one list. This should have been fixed in Mailman 3.3.6 by <https://gitlab.com/mailman/mailman/-/merge_requests/932>.
This should never happen with a post that is delivered to members without being held.
Also, I think when this happens to a delivered post, the post in the archive will also have the content lost message.
I would like to get as much information as possible about the circumstances when this happens. In particular, was the post held for moderation, was it posted to multiple lists, for how many lists was the content lost. Also, it may help to see the full raw message with the content lost notice. (If there are privacy concerns you can send these to me off list)

I asked the poster of one message what he had done. Apparently, he had put the list address (just one list, according to him) in the Bcc: field. The message was then held for moderator approval and, when approved, sent out without a body.
Another message was stopped because it did not have a subject field. Again, it was approved and then sent out without a body.
From what I can see (the hold messages are sent to me as well), the messages were stripped after approval, as the approval messages have the message bodies.
I will try to ask my moderators not to approve messages that are held by the server and instead reply to the senders and discard the messages.
Yours,
AllanP.S.: I had hoped that the upgrade would now allow the moderators to see the list of members, as that is enabled for each of my lists. It's now our top issue, with the change-of-address issue made easier. If moderators should not see the members list then maybe a third option on the menu should be 'Only list owners.' But it would be good for the moderators to see the list, as well as being able to subscribe and unsubscribe members.

I just did a test of a message with no Subject. It was held for no subject and when accepted was delivered. in all cases, the notice to the admin, the message in the held message view, the message delivered to the list members and the archived message; the message body was intact
I did the same test with implicit destination with the same result.
I even tried posting the same message to list@example.com and list+z@example.com resulting in two held messages which I accepted one at a time and the only difference was only the first accepted message was archived by HyperKitty because of the duplicate Message-ID:. Both were archived with content in the prototype archive.
If you are really on Mailman 3.3.7, your result should be the same. Even on 3.3.5 which first introduced the possibility of content being lost, this shouldn't happen on posts to a single list
You could try these same tests on a test list on your installation. I would be interested in your result. If it is the same as mine, there must be some other condition affecting this although I don't know what it would be.
