Technical Specs

IceWarp WebMail is AJAX based for improved usability and performance. Drag & Drop, automatic sign-on, periodical email checking, search, sorting, flagging, image preview and full GroupWare integration.

The latest Web 2.0 technologies for building web applications used in IceWarp WebMail not only improve performance of both server and client, but also contribute to overall system security and reliability.

AJAK Technology
IceWarp WebMail's client application consists of special JavaScript objects and communicates with the server using a proprietary, strictly-specified XML protocol.

  • Pure Web 2.0 (AJAX technology) - speed comparable to desktop email clients
  • XML server based protocol - unlimited extensibility options
  • Complete UTF8 support - any UI language and all character encodings at once
  • Multiple client certificates, server side encryption
  • HTTP, HTTPS, POP3, IMAP, SMTP protocols
  • Global admin, domain admin and user hierarchy for settings and restrictions
  • XML configuration files
  • Optimized for thousands of messages and real DB backend server
  • Simple localization process via XML files
Designed by experts in secure messaging and powered by next generation technology on server side, IceWarp WebMail is resistant to attacks, communicates securely, encrypts individual messages, protects user data and leaves no track on client computer at all.

  • SSL secured, RSA (public-private key) password protection
  • S/MIME - allows user to digitally sign/validate a message
  • Dangerous content (XSS) stripping from HTML emails
  • Strict XML request parsing
  • Potential vulnerabilities of PHP global variables disabled
  • Virtual Cookies keep user settings server-side
Client-Side Performance Optimizations
Optimized client-side processing is crucial for interface responsiveness and user experience, but also takes the load from the server, freeing its resources for other services. This means that more accounts can now be hosted on the same hardware.

Browser Support
Requires Mozilla/Firefox 0.9 or higher, Internet Explorer 5 or higher.
IE7 and FireFox 1.5+ is recommended due to compressed data stream support.
