Hi!
Usually global acls (with acl plugin) are used to prevent access to a folder. You can use "Deleted Messages" owner in global acl file to block access
I'm not trying to deny access to the folder.  I'm trying to hide it, so it doesn't show up in the client account configuration (OSX Mail)
...
and alias_for only works for namespaces.
I'm using namespace inbox

There is no "mailbox plugin", I think you've been misguided by some LLM there.
I've been following instructions from Perplexity.  this is the first time it has failed me like this

Also you could explain a bit what kind of problems you have with Sieve
well, so far I haven't been able to make it work.  I put this into /var/lib/dovecot/sieve/global:
require "fileinto";
if header :matches "X-Spam-Level" "*****" {
discard;
stop;
}
if header :matches "X-Spam-Level" "*" {
fileinto "Junk";
stop;
}
made sure LMTP is enabled and configured sieve:
protocols = imap pop3 lmtp sieve
protocol sieve {
mail_plugins = " sieve"
}
plugin {
sieve = file:~/sieve;active=~/.dovecot.sieve
sieve_before = /var/lib/dovecot/sieve/global
sieve_execute_bin_dir = /usr/lib/dovecot/sieve-execute
sieve_global_extensions = +vnd.dovecot.execute +vnd.dovecot.environment +variables
sieve_plugins = sieve_extprograms
sieve_trace_debug = yes
sieve_trace_dir = /tmp/sieve
sieve_trace_level = matching
}
but it hasn't filed anything.  as you can see I enabled a trace directory:
ls /tmp/sieve
drwxrwxrwx  2 root root  40 Sep 10 16:09 ./
but it remains empty
