The list
Yahoo Zimbra
Zimbra has a range of editions of its email client and has also developed its own mail server application. Zimbra is owned by Yahoo and currently uses a web interface, but is also available as a beta "desktop" edition which permits emails to be viewed online and offline. The web version is considered in this review.
Zimbra appears to have all the features of Outlook, including an integrated calendar and To Do list. Zimbra also claims improvements over Outlook such as not restricting mail boxes to 2GB. Despite being a web-based client, the interface supports multiple accounts including email extraction from external servers via POP3 or IMAP — providing centralised email access.
While Zimbra may not have the kind of scripting that graces Outlook, it does have customisable filters and a host of add-in Zimlets (similar to widgets found in Lotus) giving access to such things as flight bookings, Flickr, Babelfish and Yahoo Maps (IT staff with AJAX skills may be interested in Zimlet development). Another very handy feature is its integrated instant messenger. Besides three versions of English, 15 language options are available for the interface.
The online evaluation did not allow for the sending and receiving of emails at the time of testing, so it was not possible to assess the effectiveness of HTML email handling, nor has the Email Standards Project evaluated this software.
Zimbra has features that make it far more than an email client. It allows online viewing of Word and PDF documents as HTML. Zimbra also allows the creation of online documents, which includes pictures and spreadsheets. Integrated Asterisk technology allows for voice calls and messaging via existing VoIP systems.
Having a web-based interface, it is tempting to compare this product with services such as Gmail or ordinary Yahoo accounts for that matter. In fact, the feature set and flexibility of Zimbra make it more comparable with applications such as Outlook or even Lotus Notes.
Zimbra easily equals Outlook and it leaves Thunderbird for dead — aside from its inability to check messages offline. (On that note, it might be worth looking into Zimbra desktop at a later date when it completes beta testing.) Zimbra Desktop supports offline message browsing and allows users to access web accounts such as Gmail.
Both open source and paid versions of this software are available. Naturally, the open source version exists so that Zimbra's development will be accelerated — swapping expertise for the product. Purchasers of the paid versions are, of course, entitled to technical support. Being web-based, the licensing fee is for the server software rather than client software.
Zimbra Professional pricing is US$875 per year per 25 mailboxes. Pricing per person reduces as the number of users increases and discounts of 50 per cent are available to government, educational and non-profit organisations. This pricing assumes the software resides on your own server. Hosted services are also available. Given the range of features and flexibility, pricing at $US35 per user seems very reasonable.
