Roundcube — The Perfect Webmail Client for Teletom

The ideal middle ground between heavy CRM systems and outdated local email programs.

Why a Web Interface Instead of a Local Program?

Today, few people rely on local email clients like Outlook or Thunderbird. Web interfaces are gradually taking over, and for good reason: browser-based access is inherently more mobile. You can manage your email from any computer or smartphone, anywhere in the world, without being tied to a specific device or worrying about syncing settings.

Corporate clients often take this a step further by using various CRM and Ticket systems to unify different communication channels — email, messengers, calls — into a single customer management hub. However, this approach has a significant downside.

    The problem with CRM/Ticket systems: most are overly complex and expensive. Feature bloat makes them difficult to implement and learn for everyday users. Furthermore, when it comes to sending and receiving emails, these "heavyweights" introduce noticeable delays, as every message must pass through multiple internal modules before reaching the user.
  

Roundcube: A Time-Tested Sweet Spot

Within the Teletom architecture, we deploy Roundcube — a mature, open-source webmail system. It is a long-standing development that has become the de facto standard in its niche.

Core Capabilities of Roundcube

Roundcube works perfectly "out of the box," and its interface is so intuitive that detailing every button is unnecessary. Here are the key features that make email management efficient:

⚡

Instant IMAP Performance Authentication happens directly via the IMAP protocol, meaning messages are viewed, sent, and received almost instantly — much like modern messengers.

📂

Flexible Profiles & Folders Customize profiles and move entire email threads between folders. Organize your mailbox to fit any workflow.

💬

Threaded View Mode Enable threaded discussions in any folder — emails on the same topic automatically form a connected branch. It acts like a simplified ticket system right inside your inbox.

🔀

Advanced Filtering Set up auto-replies, automatic forwarding, moving, or deleting of emails based on custom rules. Let the routine run without you.

🎨

Plain Text & HTML Support Send and receive emails in both simple plain text and beautifully formatted HTML — complete with styling, images, and layouts.

🌍

Full Localization The interface is translated into dozens of languages. Work in your email client in the language you are most comfortable with.

📱

Mobile App Support Roundcube can be installed as a web app on your smartphone. It runs fast, looks native, and supports push notifications.

Exclusive Additions by Teletom Engineers

Roundcube is already an excellent tool on its own. But we went further and added two proprietary plugins that transform this web client into a truly mobile and functional solution:

Large File Cloud Integration Send large files directly through your own private cloud right from the Roundcube interface. Files up to 5 GB are uploaded and attached as links — just like major providers, but hosted on your server.

    Conclusion: Roundcube within the Teletom architecture is a ready-to-use, convenient, and lightning-fast webmail client. It is not bloated with unnecessary features, operates instantly via IMAP, is understandable to any user at first glance, and is enhanced by two vital Teletom plugins: mobile app support and private cloud for large files.
