For new accounts, dovecot only has a single default folder, the inbox.
Is there a way to specify a default set of subfolders, preferably immutable, that exist for each inbox?
Ideally, I want each account to have a Sent, Trash, and Drafts folder, which can all be read/written to, but not renamed or deleted.
In case it is relevant, my dovecot configuration specifies no subfolder prefix, so all user-created subfolders exist at the "root" level of the Maildir, which is the mailbox format I’m using.
