Latest news about Email Servers

2019. Email collaboration software Zimbra added own document editors

Zimbra Network Edition has introduced an integrated, feature-rich office productivity suite called Zimbra Docs. The remarkable aspect is that it is available for free, eliminating the need for a separate MS Office license. With Zimbra Docs, users can now effortlessly create and edit documents, spreadsheets, and presentations directly within the Zimbra platform. It supports popular document formats such as xls, doc, ppt, and more. The suite includes various apps: Zimbra Writer for document editing, Zimbra Calc for spreadsheets, Zimbra Impress for presentations, and Zimbra Briefcase for converting and sharing files. At the core of this service is the Zimbra Docs server, which must be installed on dedicated nodes running RHEL 7 / CentOS 7, Ubuntu 16.04 LTS, or Ubuntu 18.04 LTS. In addition to its built-in office suite, Zimbra also offers integration with LibreOffice, providing users with another free office suite option.

2018. IBM sold Lotus Notes/Domino, Websphere Portal and other software to HCL

IBM is in the process of selling its renowned enterprise collaboration software, Lotus Notes, to the Indian company HCL for $1.8 billion. These products have been a significant component of IBM's enterprise business for a considerable period. However, last year, IBM began divesting the development segment to HCL while retaining control over sales and marketing. With the platform's development now outside of IBM's purview and the need for funds after a $34 billion expenditure on Red Hat, it appears that IBM decided it was no longer viable to retain any part of Lotus Notes in-house. On the other hand, HCL recognizes an opportunity to further develop the Notes/Domino business and is seizing it through this acquisition. HCL's interest in Notes/Domino surpasses what IBM has shown over the past decade, as they are heavily investing in rejuvenating the brand. Notes and Domino still maintain a presence in various enterprise sectors, particularly in EMEA (Europe, Middle East, and Africa). This strategic move aligns with IBM's shift towards advancing its cloud business in a different direction. The acquisition of Red Hat in October, in particular, demonstrates IBM's focus on embracing private and hybrid cloud deployments, whereas older software like Lotus Notes and Domino have limited relevance in this new realm.

2015. Synacor acquired Zimbra

Zimbra has previously been acquired by Telligent, VMware, and Yahoo. This recent acquisition comes shortly after the announcement that Verint has acquired Telligent (Zimbra Social) from Zimbra earlier in the week.
