When subscribing to spam mailboxes, per these instructions:
- on the right side, you should see mailboxes for each Email accounts on your domain, like this: mydomain.com /joesmith/spam (assuming you have a valid mailbox for firstname.lastname@example.org)
- click on a spam box to subscribe to, and click the 'subscribe' button at the bottom of the list
What about the mailbox simply called "spam" with no user mailbox prefix? Do I subscribe to this as well?
