I have a server-side special-folder called “Junk” where spam is automatically moved by the server-side-spamfilter. eM-Client doesn’t detect this folder correct and creates a new Folder called “Junk E-mail”. How to point eM-Client to this server-side-folder and use this as junk-folder?
The option is available in your account settings. (Menu > Accounts > IMAP > Special Folders)
You will need to untick Automatically detect special folder names, and then edit the Junk option to reflect the server folder name, then restart eM Client. You may also have to edit all of the other special folders if they are not displayed after the restart. You can get this information from your email provider, as some servers have naming conventions like Inbox.Spam etc.
Dovecot is not fully compatible with eM Client. I know for sure that public folders don’t work, but I have not seen that the other special folders are not displayed in the eM Client settings.
It may be a configuration issue with the Dovecot server, but I couldn’t comment as I have no other experience with that.
