Auto-delete Spam Box emails older than x days

Introduction

You may want to add auto-delete to a few additional mailboxes for dovecot. By copying the default dovecot configuration and modifying a custom .local file, you can preserve the needed changes.

Procedure

To do this, you need to copy the main.default to main.local and customizing the [% IF expire_trash %]. You'll also need to enable the configuration option within Home » Service Configuration » Mailserver Configuration and enable Auto Expunge Trash. By default, the following is configured:

#expire_dict = db:/var/lib/dovecot/expire.db

expire_dict = proxy::expire
 expire = Trash
 expire2 = "Deleted Messages"
 expire3 = "INBOX.Deleted Messages"
 expire4 = INBOX.Trash
 expire5 = Junk
 expire6 = Spam
 expire7 = spam
 expire8 = INBOX.Junk
 expire9 = INBOX.Spam
 expire10 = INBOX.spam
 expire11 = INBOX.Sent
 expire12 0 .Sent

To create a custom template for this file, perform the following steps:

1. Copy the /var/cpanel/templates/dovecot2.3/main.default file to the /var/cpanel/templates/dovecot2.3/main.local file. This ensures that the system will not overwrite your changes when Dovecot updates during the cPanel & WHM update (upcp) process.

2. Open the /var/cpanel/templates/dovecot2.3/main.local file with a text editor. Edit the file to reflect your desired settings. For example:

   expire_dict = proxy::expire

3. Save your changes to the file.

4. Rebuild the Dovecot mail server with the /usr/local/cpanel/scripts/builddovecotconf script. This applies the new configuration settings from the /var/cpanel/templates/dovecot2.3/main.local file.

5. Restart the Dovecot mail server with the /usr/local/cpanel/scripts/restartsrv_dovecot script.
