Seven ways to push mail to the iPhone -- without Exchange

There are several options, if you know where to look

As a server, Kerio MailServer can be installed on a number of platforms, including Windows, Mac OS X and Linux. It also supports integration with Active Directory or Apple's Open Directory as well as Pluggable Authentication Module access for Linux, allowing simplified user and e-mail account management. And it supports an internal account database.

Kerio's site includes detailed instructions for using the iPhone as a client device and the company provides a wide range of configuration information and explains how to move from other mail and groupware solutions. Licensing is cheaper than Exchange and includes a variety of options such as bundled anti-virus solutions. Since the licensing is primarily user-based, there are no additional fees for mobile device or iPhone support.


Zimbra Collaboration Suite is another full-featured e-mail and groupware solution. Like Kerio MailServer, Zimbra can be installed on a number of platforms and supports a range of clients. Zimbra is available in several product editions , ranging from a basic open-source solution that does not include support for syncing data with either desktop or mobile tools to an extremely well-provisioned professional edition.

In that professional edition, Zimbra supports integration with Outlook and any Mac OS X apps that implement Apple's iSync framework, including Mail, Address Book and iCal. Unlike Kerio, Zimbra uses connector tools installed on client machines to manage data syncing with the server. And platforms other than Windows and Mac OS X will have limited access to collaborative tools beyond basic POP/IMAP for e-mail and Zimbra's rich Web interface.

Zimbra implements mobile device support, including support for the iPhone, Windows Mobile, Symbian, Palm and other devices as an optional add-on. Zimbra Mobile , as the package is called, is available for a flat $500 additional fee beyond the standard licensing terms.

Zarafa and Z-Push

Like Zimbra, Zarafa is available in both open-source and commercial variations, although it you want Outlook support, you'll need one of the commercial variations. Zarafa offers support for e-mail, centralized contacts, calendar, task management and public folders. It's designed primarily to use Outlook as a desktop client or a rich Web interface for collaborative features, and the Web interface, supports POP/IMAP access.

Dynabook Portégé X30L-G

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

This smart laptop was enjoyable to use and great to work on – creating content was super simple.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

Taylor Carr


The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
