There are a few choices: 1) Bynari Insight Server and client 2) the Oracle Collaboration Server and client 3) Using the open-source sendmail,Cyrus IMAP, and OpenLDAP plus the Oracle Collaboration Server client piece to fool Outlook into thinking it's talking to Exchange. 4) Using the open-source sendmail, Cyrus IMAP server, and OpenLDAP plus the Bynari client connector to fool Outlook into thinking it's talking to Exchange 5) Ximian's Evolution client and the above back ends.
You don't say whether you have to preserve the desktop client -- ie, do they insist on using Outlook? If no, then seriously look at Evolution. If you have to keep Outlook, then the other solutions have pros and cons. I've been very impressed with the client piece for the Oracle Collaboration Server (nee Steltor's Corporate Time client). It's very smooth and does a pretty good job of supporting most Outlook functions, and is fairly simple to push out to the desktop systems. There are some awkward bumps in deploying Bynari's client piece, but by and large it worked for simple Outlook functions. Wrt to the server back ends, the Oracle solution is fairly expensive due to the database requirement, but scales well. I find the combination of the open source back ends works well with either client, and keeps the cost more reasonable. You should plan on installing the server back end first, then pushing out the client piece, and then using the client to copy the messages from Exchange folders to folders on the new mail server as the simplest approach. Extracting the messages directly from the Exchange store is almost impossible (this also provides an incentive for people to clean out their mailboxes). -- db ----- Original Message ----- From: "Nilson Vieira" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, October 08, 2002 3:59 PM Subject: Ms-exchange clone > Hi all > > > I,m looking for a MS-EXCHANGE like application > that works on Linux suse 390. > > Can some one help-me with a roadmap to migrate from MS-EXCHANGE (including messages files) to a open-source application. > > Thanks in advance. >
