This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
QMail is not all that complicated -- but it's not easily configured and maintained as, say... MS EXCHANGE! (sarcasm intended).
If you need help using/configuring QMail, try the QMail Toaster (qmailtoaster.com).
I won't go into whether QMail is better than Postfix (or sendmail... or even Exchange for that matter): that's a "religious opinion" akin to choosing a Linux distribution... I will just say that QMail installations outnumber Postfix installations nearly 3-to-1 in the most recent "open port poll" (QMail is generally believed to be the 3rd most popular MTA on the Internet -- behind sendmail (the grand-daddy of them all) and Exchange!)
As for "migration" here are my thoughts:
- attempting to get user information transferred over from Exchange to ANY other system would be a headache far worse than you are likely prepared. I suggest you export your e-mail addresses to a text file and use the command-line interfaces for QMail to re-enter them.
- your next issue will be passwords -- do yourself a favor and just make users enter a new password. Trying to export passwords from Exchange is a true nightmare -- and when you think about it, it is rightfully so, from a security standpoint!
- finally, you'll want/need to get OLD messages exported from Exchange to QMail. You can try to automate this using something like qpopper, but again, I recommend just letting your users do it. They can have temporary access to BOTH servers and just drag/drop the messages from one to the other.
Just my thoughts -- they're worth every penny you paid for them!

Step 2: Hire a consultant
tasks like that are not for the faint of heart.
Just bein' honest.
if its an enterprise grade system, you need to make sure everything touching the exchange server moves without an issue. qmail is a thorny, nasty, messy beast.
you want someone who's done this before, and knows all the pitfalls because they've fallen in the pits before.
watch out for calendaring--exchange is VERY good at it, and few other tools are. also look at your ldap & security policies, you may have lots of things tied in there you're not aware of.
