One of the Dovecot repository maintainers on GitHub recommended sending an eMail to you regarding the issue I encountered:

Documentation for lazy-expunge doesn't work https://github.com/dovecot/documentation/issues/1555

I converted from Dovecot 2.3 to Dovecot 2.4.1, which was not a minor upgrade. Anyway, I can't get the lazy-expunge plugin to work in 2.4.1 now. Here's my configuration file from 2.3 -- how can I get this working in 2.4.1? Thanks.

namespace inbox { mailbox EXPUNGED { autoexpunge = 32days autoexpunge_max_mails = 100000 #auto = create } }

Namespace for lazy_expunge plugin

namespace { prefix = EXPUNGED/ hidden = yes list = no subscriptions = no separator = / location = maildir:~/Maildir.deleted:INDEX= }

mail_plugins = $mail_plugins lazy_expunge acl plugin {

Move expunged messages into the .EXPUNGED namespace

lazy_expunge = EXPUNGED/

Only move to expunged storage if this is the last copy of the

message in the user´s account lazy_expunge_only_last_instance = yes

Exclude Drafts from lazy expunging

lazy_expunge_exclude = \Drafts

Copy of each message is done with hard links whenever possible

maildir_copy_with_hardlinks = yes

Define ACL so that user cannot list the .EXPUNGED mailbox

Example entry: .EXPUNGED owner rwstipekxa

acl = vfile:/etc/dovecot/dovecot.acl

dovecot.acl contains one line: EXPUNGED owner ip

Expunged messages most likely don't want to be included in quota:

quota_rule = EXPUNGED:ignore } #lazy_expunge_mailbox = EXPUNGED

Here's an example of someone else who encountered the same problem: https://www.dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thr ead/25BXSHQWGQQ3ACVZSYF3O3LC4WROTUCI/
