Greetings,

I am unable to completely migrate my Dovecot 2.3 config to 2.4.1 as I'm unable to get past the following error:

Error: Namespace inbox: maildir: maildir settings: Failed to parse configuration: Failed to override configuration from userdb: Invalid maildir=${domain}/${user}/: Setting is a named filter, use 'maildir {'

I found a similar encounter at https://www.mail-archive.com/dovecot@dovecot.org/msg90843.html that points to https://doc.dovecot.org/2.4.0/core/config/mailbox/mail_location.html#per-use... yet I still can't get my config to work. I've attached my doveconf at the end, including the ported 2.3 settings that used to work for me (commented out).

I would appreciate any advise.
