Hello. We have a brand new (as of last week) Mailcow-dockerized installation on Debian having moved from Iredmail that we used for about 6 years. So far, I’m loving it and have only run into one issue I can’t seem to find any information on. My understanding is that if an item is moved from the junk folder to the inbox it should be learned as ham and stay in the inbox. What happens here is that the item goes right back to the junk folder immediately. This behavior seems independent of the client as it occurs in both Sogo and Thunderbird. We don’t seem to have a way to move item marked as Junk to the inbox permanently. While I don’t know for sure that such items are not being learned as ham, I suspect not. The behavior suggests that the item is immediately seen as spam in the inbox, and moved right back to junk.
Any insight would be greatly appreciated!
