What is IceWarp?

At the core of IceWarp's messaging platform is a scalable and robust SMTP/IMAP/POP3 server capable of handling 1000's of messages per minute in multiple outgoing queues. All services are secured with SSL/TLS encryption, supporting deployment of any kind, from mail relays, integration to websites, up to load-balanced platforms and geographically dispersed architectures.

IceWarp can be deployed in cloud or on-premise with support for Windows 2003 and later, Red Hat Enterprise Linux, CentOS, Debian and Ubuntu. It's available for 64-bit or 32-bit operating systems and connects to MySQL, MS SQL, and Oracle databases.

Documents can be open and edit directly in the browser window. Easily multitask with emails, files and online meetings. Cooperate on a document with the team – lock it, save multiple revisions, roll back to an earlier version or share it in TeamChat and let others comment on it.

TeamChat is a real-time messaging and collaboration tool for teams & projects. It lets you get in touch with other people on the team, organize your conversations around one topic, share files or create ad-hoc meetings.

WebClient centralizes all your data and communication be it email, chat or calls and makes it accessible from any browser or device. Manage emails, contacts, appointments, tasks and notes, while in a chat or in a web meeting – no need to switch between tabs or windows. One unified interface, optimized for mobiles and tablets. It has a full feature set for personal information management including calendaring, resource planning, contacts, tasks and notes. All information can be easily shared among users via Global Address Lists, Group Calendars or Public Folders.

With IceWarp WebDocuments, you can work with all documents online without the need to install an Office suite. Share files with others internally or use SmartAttach technology to send large files by email.

When i'm writing this, i'm using IceWarp for 6 months. Although there are desktop apps, i only use the WebClient. One tab in the browser to work with mail, calendar, notes, Office documents, teams, chat, VOIP and webmeeting.

Teamchat and webmeeting works also when someone does not have an IceWarp account.

But one of the briljant features is smartattach. If you want to deliver a large mail, you do not have to think about it. Jus mail it. IceWarp does not sent the attachment but automatically creates a link. The recipient gets an e-mail with a download link.
