hidden / alias_for / sieve

11 Sep 2025

      hi.  I'm running on Fedora 42 and want to hide the Deleted Messages folder (because I want to use Trash instead).  unfortunately this fails:
mailbox "Deleted Messages" {
hidden = yes
}
which I understand depends on the "mailbox" plugin.  however, when I look in /var/lib64/dovecot, I don't see any such plugin.  I also cannot find in the repositories any RPM that provides it.  I understand it may be baked into the core binary but if so, enabling it should work, and yet if I do enable it, I get the error below:
Sep 11 10:06:01 mail dovecot[739762]: imap(ekkis): Error: Plugin 'mailbox' not found from directory /usr/lib64/dovecot
I would also like to use the alias_for but that also fails. sigh.  I'm also struggling to make Sieve work.  I've produced a sysreport (see: https://arix.com/tmp/dovecot-sysreport-mail.arix.com-1757611127.tar.gz) and you'll find my config file below:
