Migrate postfix to Exchange
I have Deployed a new Exchange 2003 server to a company that is currently using Postfix as their mail system. www.postfix.org
I am looking for a WINDOWS GUI to transfer these IMAP accounts to their new mailboxes on the Exchange 2003 server. Anyone aware of such a tool/utility?

Can you elaborate a litte bit? I found the mailmig.exe file in SP2.
It's asking for a CSV file. What info needs to be in the CSV? I'm not sure how to format that. A link to documentation would be helpful.

I ran into the same problem and it took multiple web pages to get all the syntax and concepts correct: I'll boil it down here then post some links (Gotta find them again). I was only able to get the 2 step process to work (I never followed up with the 1 step process):
2-step method
Step 1 : Run the Mail Migration tool and Generate 'Migration Files' or create them by hand.
Step 2 : Run the Mail Migration tool again and 'Import from Migration Files'
The LDAP and IMAP4 options are for Step 1 above. They create the Migation files.
Here is what I imported (The contents of Imapusr.csv, HEADERS ARE REQUIRED!!)
IMAP_Mailbox,SMTP_Address,
frashii@frashii.com,frashi
This is how the mgiration wizard knows what accounts to import and what credentials to use to get them.

I remember reading these exact articles when I did this last time :

Well, here's an update. I was able to extract a mailbox without error from postfix but when I tried to convert the migration files to a PST, I received a ton of these errors.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
I used it to migrate unix based imap mailboxes (Dovecot w/ exim) and would imagine it will do Postfix w/ whatever you are using for imap.
