Sorry, this one kinda dropped thru the cracks. I was traveling a lot in early December.<br />
<br />
Never used Scalix.<br />
<br />
Looked at NetMail fairly closely. Looks good, but it wasn't what we needed for our environment. HULA is the open-source version of NetMail.<br />
<br />
Never used OpenExchange.<br />
<br />
GroupWise is a good, multi-platform collaboration environment.

I've been given the task of allowing users to share calendars using outlook. &nbsp;We run a simple pop and imap server right now. &nbsp;I am looking for an exchange server replacement for linux. &nbsp;I need a pop/imap server, web interface (would be nice if it would have the calendar as well), spam (pref. spam assassin), virus, authentication, etc. and allow for us to share calendars. &nbsp;Does such a thing exist?<br />

Exchange server replacement for linux

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
