I just finished installing zimbra on Gentoo. It works great.
On one other server I have about 300 user accounts with user names and password stored in vpopmail database and table. How to import this user accounts into zimbra? I do not need user messages I just need there passwords and accounts. And one more thing passwords are encrypted.
I was looking all around wiki and forums and I found imapsync. It is working great for user messages from mailbox from one server to another. BUT THIS IS NOT WHAT I NEED.
This is what I need: Qmail (vpopmail) acounts --->> Zimbra accounts
