Re: Linux Exchange server replacement.
Sorry to dredge it all up, but there was a discussion some time back about an app that was supposed to be a drop in replacement for ES including all of the calendaring crap. Does anyone remember what that was? PostPath (http://www.postpath.com) advertises on their homepage: The only Exchange Server™ alternative to deliver drop-in Microsoft(r) interoperability across the email ecosystem. A free 12 user version can be downloaded from the site When I looked at this though, about 6-9 months ago, I found out that this still relies on an MS active directory infrastructure already in place. I did speak with a salesman from the company and he did tell me that a completely stand alone version was planned for release in 2007. Hope this helps.

Another option is Open Xchange. It's actually a bit of a superset of Exchange in that it offers some features not available in Exchange.

O... shiny. /me moves Look at PostPath up a few notches on my to-do list (Unfortunately, that still means Possibly not within this decade. ~sigh~) If even a portion of following is true, I'd be an extremely happy sysadmin: The server's high performance (compared with Exchange) and ease-of-backup enables the use of low-cost storage, server consolidation, and significantly larger user data-stores so that PST-file use can be reduced or eliminated. Also, the server's flexible translation between Microsoft (ESTMP) and standard (SMTP) email transports, together with a highly configurable PostFix mail transport agent (MTA), enables the use of standards-based virus-filters and archiving systems, eliminating the need for Outlook journaling or proprietary APIs. Somethings to note: - High performance as compared to Exchange is not difficult to achieve :) - Ease of backup is a major win compared to Exchange - Reducing or eliminating PST file use is huge - Eliminating the need for Outlook journaling and the use of MS APIs is huger - The acknowledgement of the use of Postfix (or any mainstream open source MTA) is a great endorsement - The actual use of a mainstream MTA means we can probably tweak this thing to our heart's content! - There is no mention of IMAP capability, nor of calendaring, yet they claim Drop-in, plug-compatible replacement. (There is a POP3 server though) - They do discuss the ability to work with both an existing AD server, and Blackberry server. - The admin manual has details on backing up via tar, dump, xfsdump, legato7, fs, and Symantec BackupExec, which means that Bacula and AMANDA should work just fine. After looking over their FAQ (which is available only as a PDF http://static.postpath.com/gems/apptranMain/PostPathFAQv04.pdf and their Admin Guide http://static.postpath.com/gems/apptranMain/PostPathAdminGuide.pdf I'm left with some conflicting thoughts. I think it's great they've got this product, and I think not having to deal with Exchange is great. However, there is no Exchange-PostPath Feature comparison. Calendaring is HUGE in the MS world. MS users can not live without it. Yet, there is no mention of this one killer feature of Exchange that I found. Next, all the documentation seems to be geared those used to managing Exchange, and therefore assumes little to no Linux, UNIX, or FOSS familiarity. Yet there is no mention of which e-mail clients PostPath is compatible with other than Outlook, and there is no mention of how a non-Windows desktop (Mac, Linux) could or should connect to the PostPath server. Their FAQ is hardly useful[1], their Admin Guide seems not bad. But there are still a lot of unanswered questions, like, what if I'm in a non-windows environment and want to provide an Exchange-like service ? Can I do that? If so, what client-side software is compatible? Can I use a combination of IMAP client and Web-browser to deal with e-mail and calendaring? Will Evolution work? Does it need the Exchange Connector software, or is that unnecessary? So, at this point, I think what they have is something that probably works really well as an e-mail server for Outlook-based clients, is far easier to back up. And in some ways that alone is a major win. However, I'm left with the feeling that this product is more for people who don't know and understand e-mail beyond the level a point-n-click than those of us who have pulled our hair out tweaking sendmail.cf and making postfix jump through hoops over the years. -- Seeya, Paul [1] A FAQ from a commercial entity which is mostly useless is not a surprise.

Re: Linux Exchange server replacement.
Oooh, interesting. Open Xchange does NOT speak MAPI. You need to use either POP or IMAP for email connectivity. It uses WebDAV for the calendar, shared folders, and other features.

It might be worth noting that Outlook implements calendaring as just another class of the same IPM object that regular messages are. Meeting invitations are just special hidden messages. Free/Busy Information is just IPM objects written to a hidden Public Folder. The Exchange server itself has very little awareness of the calendaring. So if they've got the Exchange wire protocol working, they might not need to worry about it; it's mostly done in Outlook. (Of course, there are probably details that matter, but I figured I'd toss this out there). But there are still a lot of unanswered questions, like, what if I'm in a non-windows environment and want to provide an Exchange-like service ? Given the reported Active Directory requirement, I'd say you're in trouble. ;-) -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Linux Exchange server replacement.
I installed and tested Zimbra.. It didn't have support for a few things we needed at the time (like truly shared calendars). It's my understanding that this has been corrected in the recent versions. They have a free demo you can test out. The web interface is very impressive.
