If you’ve deployed a Nextcloud server, you’ve probably discovered that it can be scaled beyond simple cloud storage. In fact, there is a full app store available for Nextcloud, and you can install a number of apps and services that go a long way in expanding your cloud server. One of these applications is RainLoop Webmail.

With the addition of this awesome app, you can transfer your preexisting webmail from your domain to the Nextcloud framework, so users just need to login to Nextcloud, click to open the RainLoop app, login to their webmail account and manage their email from Nextcloud.

If you are looking for an all-in-one cloud location, RainLoop will be a great addition. Let’s install RainLoop and connect it to your domain.

How to install the RainLoop app

To install RainLoop Webmail, you must have access to an administrator account for your Nextcloud server. Once you have done that, log into Nextcloud and follow these steps.

  1. Click the Applications drop-down menu in the upper left corner.
  2. Click the + button.
  3. Click on Social networks and communication in the left pane.
  4. Locate RainLoop and click the Activate button.
  5. Let the installation complete.

How to configure RainLoop

Now that the app is installed, it’s ready to be configured.

Click the Applications drop-down menu and click Email – this will present you with a login window. RainLoop will be configured with admin / 12345 administrator credentials. Enter administrator for the user and 12345 for the password and press Enter on your keyboard.

You will be logged in and immediately prompted to change the administrator password – change that password, and you are now ready to configure RainLoop to include your domain. At this point, you can also configure the brand, enable contacts, security, Google integration, etc.

The first thing you’ll want to do is add your domain for Webmail integration. To do so, follow these steps.

  1. Click on Domains (in the left navigation).
  2. Click Add Domain.
  3. In the window that appears, configure your domain (Figure A).
  4. Once the configuration is complete, click Add.

Adding a domain in RainLoop.

When adding a domain, it is important that you add the correct information for the name. If the domain you are adding is domain.com, you must enter domain.com as the name. Entering a nickname for the domain here will result in a login failure. In addition, some domains do not allow the use of a short login (username vs. username @ domain). If your domain requires a full email address for connection, do not enable the Use short connection option.

After adding the domain, your users can log into their email accounts through RainLoop in Nextcloud.

How to enable Gmail two-step authentication in RainLoop

The Gmail domain is included with RainLoop. If a user has two-step authentication enabled on their Gmail account (which they should do), users must sign in to their accounts using a Google-generated app password. Once a user logs in with this method, they will be prompted to enable their two-step authentication (Number B).

After clicking Activate, you will be prompted to scan a QR code in the Google Authenticator app and two-step authentication will be added.

Note that users will create a separate, RainLoop-specific two-step authentication instance for their Gmail account in Google Authenticator. Also note that the generated app password will be the password used for RainLoop and not its regular Gmail password.

How to log in to RainLoop

To log into RainLoop, a user must follow these steps.

  1. Log into their Nextcloud account.
  2. Click the Applications drop-down menu and select Email.
  3. When prompted, enter the necessary credentials to sign in to their webmail account (Figure C).

At this point, your users can take advantage of the built-in webmail in Nextcloud. You can add as many domains as you need (and even include Google integration), so add all your business email domains to make this one-stop shop even more powerful.

A constantly expanding platform

As Nextcloud continues to grow into a truly impressive ecosystem, you will find more options to entice you to deploy this cloud platform. With the addition of the RainLoop Webmail app, your users can work within a single system for even more work.
