We have been doing a manual migration of a qmail system with 1100 users to Zimbra. We have manually made all these accounts on Zimbra and moved their passwords over and everyone is sending/receiving mail okay. The only issue is there are some emails sitting in the users/<username>/Maildir/new/ that we want to move over.
The old qmail system is pop3.
We want to move mail from qmail to Zimbra for 844 users. I looked at pop2imap to do this but it seems like I will still have to manually create 844 folders in Zimbra.
Your advice on the best way to go about this would be really appreciated.
