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
