Roundcube Webmail Hosting Live In 5 Minutes

Roundcube Webmail hosting gives your users a browser mail client on your own domain, connected to the IMAP and SMTP service you already run. Deploy Roundcube Webmail 1.7.3 as a self-hosted webmail client: xCloud runs the pinned non-root image with a private MariaDB 11.8.3 database, wires in the mail hosts you enter, generates the encryption key and database credentials, and publishes it over HTTPS.

What is Roundcube Webmail?

Self-hosted Roundcube Webmail is a webmail client. Its README calls it a browser-based multilingual IMAP client with an application-like interface, offering MIME support, an address book, folder management, message searching and spell checking, with a plugin API and skins. Organisations use it to give people a browser mail client on their own domain, as an alternative to Gmail's web interface, for a mail service they already run.

On xCloud the template runs the roundcube/roundcubemail 1.7.3 non-root image beside a private MariaDB 11.8.3 database, both pinned by immutable digest. The roundcube_db and roundcube_config volumes persist preferences, address books and custom configuration. HTTPS is published on your domain. It runs no mail server and creates no mailboxes: users sign in with accounts on the IMAP server you configure.

From Sign-Up to a Live Webmail Client In Just 3 Easy Steps

A webmail client normally means two containers, a database, an encryption key, server settings, two volumes, a domain and a certificate before the first inbox opens. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Roundcube from the OneClick catalog. Choose your domain and target server, then set the IMAP Host, IMAP Port, IMAP Encryption, SMTP Host, SMTP Port and SMTP Encryption.
Step 02
We Deploy It For You
One click. We bring up the official Roundcube 1.7.3 image, pinned by immutable digest with a pinned MariaDB 11.8.3 database on the private Compose network, mount the roundcube_db and roundcube_config volumes, and publish it over HTTPS on your domain.
Step 03
Sign In With A Mailbox
Open your domain and sign in with an account that already exists on the IMAP server you configured; Roundcube reuses the same credentials for authenticated SMTP. Confirm folders load and send a test message.

Everything Roundcube Does, On Your Own Server

Roundcube runs in full here: mail, folders, contacts, identities and preferences, on a database you own, against the mail service you already have.

Full Webmail
Read, organise and send mail in a modern browser interface on your domain.
Contacts And Identities
Address books, identities and preferences stored in the private MariaDB database.
Your Existing Mail Service

What You Can Do With Roundcube Webmail

Give staff a browser mail client
Point Roundcube at the company's IMAP and SMTP service so staff read and send mail from any browser on your own domain, using the mailbox accounts they already have.
Put a branded front end on existing mail
Keep your current mail provider and add a webmail address under your own domain, customised with skins, without moving a single message off the provider's IMAP server.
Manage contacts and folders in one place
Use the address book, folder management and message search described in the README, with preferences and contacts stored in your own MariaDB database on a dedicated Cloud VPS.
Extend webmail with plugins
Use Roundcube's plugin API to add features the core lacks, keeping custom configuration on the roundcube_config volume so it survives restarts and redeploys.

Roundcube Webmail vs Alternatives

Gmail: Choose Roundcube as a Gmail alternative when you want webmail on your own domain. Roundcube is a client only: it fronts an IMAP and SMTP service you choose, with your preferences and contacts held in a database on your own server.
SnappyMail: SnappyMail has its own xCloud template. Roundcube's README lists a plugin API and skins, and this template backs it with a private MariaDB database for preferences and address books.
SOGo: SOGo has its own xCloud template. Roundcube here is a mail client with an address book, so choose it when you only need webmail over an existing service.
Mailu: Mailu has its own xCloud template. Roundcube runs no mail server, so it needs an IMAP and SMTP service to connect to, whether you host one or use a provider's.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

How much RAM does Roundcube Webmail need?

Roundcube's manifest floor is 1 CPU core, 1024 MB of RAM and 10 GB of disk, covering the webmail container and its MariaDB database. The 6 GB Cloud VPS that this page sells sits far above it, so more concurrent sessions and larger address books fit without resizing.

Is Roundcube Webmail free and open source?

Yes. Per its README, Roundcube Webmail is free software under the GNU General Public License, with an exception for skins and plugins that only call its functions. Nothing is charged for the software; xCloud bills for the dedicated Cloud VPS it runs on.

Does Roundcube Webmail include a mail server?

No. Roundcube is a client for an existing service. You enter your provider's IMAP and SMTP hostnames, ports and encryption modes at install, the template creates no mailboxes, and messages stay on the external IMAP server rather than in this install.

Can you run Roundcube Webmail with Docker?

Yes, and this is Roundcube Webmail Docker hosting prepared for you: the template runs the roundcube/roundcubemail 1.7.3 non-root image beside mariadb:11.8.3, both pinned by immutable digest, with roundcube_db and roundcube_config volumes and HTTPS in front on your domain.

Which databases does Roundcube Webmail support?

Per its README, Roundcube requires MariaDB, MySQL, PostgreSQL or SQLite. This template uses a private MariaDB 11.8.3 container with no published port, holding preferences, address books, identities and cached metadata, so you do not provision a database yourself.

Can Roundcube Webmail connect to my existing IMAP and SMTP provider?

Yes. The install form asks for IMAP and SMTP hosts, ports and encryption. Defaults are IMAP over TLS on 993 and SMTP with STARTTLS on 587. Users sign in with mailbox accounts that already exist on that server, and the same credentials authenticate SMTP.

Does Roundcube Webmail support plugins and skins?

Yes. Its README describes a plugin API for extending it and a user interface that skins can fully customise. The template keeps custom configuration on the roundcube_config volume; it preinstalls no extra plugins, so review any plugin you add for compatibility.

What should I back up on a Roundcube Webmail server?

A backup is roundcube_db (preferences, contacts, identities, cached metadata) and roundcube_config together, plus the generated DES_KEY. Email messages remain on the external IMAP server and temporary attachments are ephemeral by design, so those need no copy here.

Backups in xCloud

How do I upgrade Roundcube Webmail?

Nothing upgrades it for you: the template pins 1.7.3 by immutable digest. Back up both volumes, read the upstream UPGRADING notes and release notes, then adopt a newer template version when one is published. Keep DES_KEY unchanged throughout.

Does Roundcube Webmail store my email?

No. Messages stay on your IMAP server; Roundcube stores only preferences, address books, identities and cached metadata in MariaDB. No mailbox passwords are collected at install, because users type their own credentials at sign-in, and DES_KEY protects stored session data.

Is this Roundcube Webmail cloud hosting?

It is your own Roundcube on a dedicated Cloud VPS that xCloud provisions, not a shared hosted mail service. The container, the MariaDB database, the volumes and the encryption key belong to your install, and the webmail is served over HTTPS on your domain.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
