migrating from exchange 5.5 to linux solution

[scooby]

I've tested openexchange 4 from Suse. I'm trying to find a migrating solution but have yet to find it. Have any of you migrated from MS to a linux solution? Any suggestions?

Thanks

There are comparable packages, but it requires some tinkering to find out what you want and what works the way you want it to.

As for the mail, there are lots of imap servers and lots of SMTP server options. Personally I use Postfix+BincIMAP. However it doesn't support shared folders (yet) so you'd be in the market for another server instead if your users actually use that stuff.

For the calendars, scheduling, etc. that's all integrated in the the M$ client, will you find equivalent packages with equivalent features in Unix alternatives? Yes. Take a look at phpgroupware, for an example. Will you find it all integrated into the user's mail client for them? No.

It's a question of how much of exchange do your users use and how easily (if at all) you can wean them off of their dependance on Outlook .

You can get the same functionality in web-based applications for the 'extra' stuff, you can get IMAP. You can't get it all rolled into Outlook or any other client. That may change someday, I know that Novell has products that directly compete with Exchange and match all of its features, but not all of them have been ported to Linux yet (although they have announced that they will be since Novell has acquired SuSE). But then again, Novell's mail suite is also a commercial product and not free, so if free is what you're looking for then get ready to spend about a month downloading every mail package you can find to test what you can do with them and if they're enough for your needs .
