ownCloud Mail

An email app for ownCloud (minimum version 8.0 & PHP 5.4).

Why is this so awesome?

• 🚀 Integration with other ownCloud apps! Currently Contacts & Files – more to come.
• 📥 Multiple mail accounts! Personal and company account? No problem, and a nice unified inbox.
• 🔒 Send & receive encrypted emails! Using the great Mailvelope browser extension.
• 🙈 We’re not reinventing the wheel! Based on the great Horde libraries.

And in the works for the coming versions:

• 📚 Proper grouping of message threads
• ⚡ Caching to make everything faster
• 📎 Even better attachment support
• 📅 Calendar integration
• 📦 Folder management & moving mails

Installation

In your ownCloud, simply navigate to »Apps«, choose the category »Productivity«, find the Mail app and enable it. Then open the Mail app from the app menu. Put in your email account credentials and off you go!

Troubleshooting

Gmail

If you can not access your Gmail account use https://accounts.google.com/DisplayUnlockCaptcha to unlock your account.

Outlook.com

If you can not access your Outlook.com account try to enable the 'Two-Factor Verification' (https://account.live.com/proofs/Manage) and setup an app password (https://account.live.com/proofs/AppPassword), which you then use for the ownCloud Mail app.

Dovecot IMAP

If your Dovecot IMAP server prefixes all folders with INBOX, ownCloud Mail does not work correcty.

Check /etc/dovecot/dovecot.conf:

namespace inbox {
        separator = .
        # All folders prefixed
        # prefix = INBOX.
        prefix =
        inbox = yes
        type = private
}

Developer setup info

Just clone this repo into your apps directory (ownCloud core installation needed). Additionally, npm is needed for installing JavaScript dependencies. On Debian and Ubuntu Systems it can be installed with the following command:

sudo apt-get install nodejs-legacy npm

Once npm is installed, PHP and JavaScript dependencies can be installed by running

make optimize-js

Nightly builds

Instead of setting everything up manually, you can just download the nightly builds instead. These builds are updated every 12 hours - 00:00 (12:00 AM) and 12:00 (12:00 PM) UTC+0200, and are pre-configured with all the needed dependencies.

1. Download
2. Extract the tar archive to 'path-to-owncloud/apps'
3. Navigate to »Apps«, choose the category »Productivity«, find the Mail app and enable it.

The nightly builds are provided by Daniel Hansson

Resetting the app

Connect to your database and run the following commands (oc_ is the default table prefix):

DELETE FROM oc_appconfig WHERE appid = 'mail';
DROP TABLE oc_mail_accounts;

Go to ownCloud Mail in the browser and run this from the developer console to clear the cache:

localStorage.clear();

Configuration

Certain advanced or experimental features need to be specifically enabled in your config.php:

Debug mode

You can enable IMAP backend logging. A horde.log will appear in the same directory as your owncloud.log.

'app.mail.imaplog.enabled' => true

Server-side caching

Mailbox messages and accounts can be cached on the ownCloud server to reduce mail server load: This requires a valid memcache to be configured

'app.mail.server-side-cache.enabled' => true

Use php-mail for mail sending

You can use the php mail function to send mails. This is needed for some webhosters (1&1 (1und1)):

'app.mail.transport' => 'php-mail'
