Hi all, my mail host automatically files mails that are addressed to mail+filter@example.com into a folder named "filter". Thunderbird does not display these folders by default. If I open the subscriptions for the account, the folder is displayed and marked by the subscription checkbox. Unsubscribing and resubscribing is necessary to display the folder. In the account's Advanced Server Settings, I have unchecked "Show only subscribed servers" in an attempt to make the folders show up by default, but this was unsuccessful. Any help to make these folders show up automatically would be appreciated.
