General (All backends should apply these steps)

Update /etc/iredmail-release with new iRedMail version number

iRedMail stores the release version in /etc/iredmail-release after installation, it's recommended to update this file after you upgraded iRedMail, so that you can know which version of iRedMail you're running. For example:

# File: /etc/iredmail-release

0.9.3

Upgrade iRedAPD (Postfix policy server) to the latest 1.7.0

Please follow below tutorial to upgrade iRedAPD to the latest stable release: How to upgrade iRedAPD-1.4.0 or later versions to the latest stable release

Detailed release notes are available here: iRedAPD release notes.

Upgrade Roundcube webmail to the latest stable release

Please follow Roundcube official tutorial to upgrade Roundcube webmail to the latest stable release immediately: How to upgrade Roundcube

[TODO] Amavisd: Fix incorrect setting which signs DKIM on inbound messages

With these changes, Amavisd will aply policy bank 'ORIGINATING' to emails submitted through port 587 by smtp authenticated user. This way we clearly separate emails submitted by smtp authenticated users and inbound message sent by others, and Amavisd won't sign DKIM on inbound message anymore.

Dovecot: Fix incorrect quota warning priorities

iRedMail configures Dovecot to send warning message to local user when the mailbox quota is 85%, 90% or 95% full, but the priorities is wrong. Please fix it with steps below.

    quota_warning = storage=85%% quota-warning 85 %u
    quota_warning2 = storage=90%% quota-warning 90 %u
    quota_warning3 = storage=95%% quota-warning 95 %u

quota_warning has the highest priority, quota_warning3 has the lowest priority. Only the command for the first exceeded limit is executed, so we must configure the highest limit first.

With above setting, when the mailbox quota goes from 70% to 98% directly, it sends warning message to notify user that the quota is 85% full, this is wrong, it's expected to be warned as 95% full instead.

    quota_warning = storage=95%% quota-warning 95 %u
    quota_warning2 = storage=90%% quota-warning 90 %u
    quota_warning3 = storage=85%% quota-warning 85 %u

Restart Dovecot service is required.

Dovecot-2.2: Add more special folders as alias folders

Note: This is applicable to Dovecot-2.2.x. if you're running Dovecot-2.1.x or earlier versions, please skip this step.

Check Dovecot version number with below command first:

# dovecot --version

Open Dovecot config file /etc/dovecot/dovecot.conf (Linux/OpenBSD) or /usr/local/etc/dovecot/dovecot.conf (FreeBSD), find below setting:

namespace {
    type = private
    ...
    inbox = yes
    ...
}

Add below alias folders inside the same namespace {} block:

    mailbox "Sent Items" {
        auto = no
        special_use = \Sent
    }

    mailbox "Deleted Messages" {
        auto = no
        special_use = \Trash
    }

    mailbox "Deleted Messages" {
        auto = no
        special_use = \Trash
    }

    # Archive
    mailbox Archive {
        auto = subscribe
        special_use = \Archive
    }
    mailbox Archives {
        auto = no
        special_use = \Archive
    }

Restart Dovecot service is required.

[OPTIONAL] Fixed: Not preserve the case of ${extension} while delivering message to mailbox

With iRedMail-0.9.2 and earlier releases, email sent to user username+Ext@domain.com (upper case E) will be delivered to folder ext (lower case e) of username@domain.com's mailbox. This fix will preserve the case of address extension.

# Use dovecot deliver program as LDA.
dovecot unix    -       n       n       -       -      pipe
