best practice purging only moved messages
by Marc 18 Mar '21

18 Mar '21

If I move a message from the 'inbox' namespace to my 'archive' namespace. The message is expunged at the 'inbox' namespace and added to the 'archive' namespace. What is the best way to only purge messages that have been moved. (I do not want to purge emails that have been deleted yet)

How can I migrate mailboxes after changing hierarchy separator?
by Popkornium18 17 Mar '21

17 Mar '21

Hi, I had a common problem (folders can't contain dots) and the obvious solution seems to be changing the hierarchy separator and using the listescape plugin. My question is: Do I need to take any extra steps after changing the separator to migrate my existing mailboxes? If so, which? I tried just simply renaming the folders and doing a `doveadm force-resync` but that did not work as intended. Afterwards I wasn't able to subscribe to any of my folders, so I guess that isn't the way to go. Kind regards Simon

inconsistency in reporting from mdbox_deleted

feature request: prevent linking of email
by Marc 17 Mar '21

17 Mar '21

What I have been doing wrong with testing expunged emails, is working with linked copies of emails. Although thunderbird copies the message, it looks like the message is NOT copied but linked. If I drag 3 emails from my desktop to a folder INBOX/test4 and copy 1 message from INBOX to INBOX/test4. I have 4 messages in this folder. I now shift+del this folder. The expunged messages listing gives me the expected 3 messages doveadm -o mail_location=mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=0 vsize=0 Drafts messages=0 vsize=0 INBOX/test2 messages=0 vsize=0 Junk messages=0 vsize=0 Trash messages=0 vsize=0 test3 messages=0 vsize=0 test1 messages=0 vsize=0 RESTORED messages=0 vsize=0 INBOX messages=3 vsize=18079344 Lets recover these: doveadm -v import -u testtest 'mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index' RESTORED ALL Now I have 3 messages back, as expected. From an end users perspective if you delete a folder with 4 emails, you want your restored backup to have 4 emails, not 3 because one is already somewhere else in your folder/mailbox structure. The reason for copying an email to a different folder is that it is important. You do not want to loose it, and you want to be able to find it there. It is wrong to assume that a user will notice that these emails are missing and should look for them elsewhere. Say you have folder for a court case, and you copy emails there relevant for the court case. How can you ever know after a restore that a few email are missing from the folder, and which ones. I think it is bad this email is currently 'lost'. I rather have an option in dovecot that disables this hidden 'deduplication' feature. I think this should be the default setting also. This current deduplication feature also is hazardous because if this one copy of the email gets corrupted on the storage, you have no copies left. That is exactly the opposite of what user wants to accomplish with creating a copy. Feature request: disable this automatic linking of emails between mailboxes. Feature request: set this as a default.

I am trying to have mail from several shared mailboxes show up in a user's INBOX if they are unread or younger than 24h, using the filter "or (unseen) (all younger 86400)".
