I've set up Zimbra for our company and it's running fine. Also, my colleagues and I are quite pleased with its features, so that we've decided to migrate our existing accounts to Zimbra.
Our accounts are on a vpopmail server, the messages are stored in the Maildir format. I use this script to migrate the Maildir folders. As for now, I'd just like to make a few test runs to see if everything works all right. I have, however, encountered the following problem:
In the first test run, I migrated a single existing account, which worked fine. The imported messages appeared in a separate folder after that. It was only after that test run that I discovered that I didn't have any sent messages or saved drafts in that particular account, which therefore made a bad example. So I deleted the folder with the imported messages from within my Zimbra account, created a draft and a sent message and tried again. This time the sent message and the draft got imported to the correct Zimbra folders but I don't see the messages from the inbox - not in the Zimbra Inbox folder and not in a separate folder which I had deleted previously, after the first import attempt.
Does Zimbra keep some kind of cache that prevents subsequent imports of messages that had already been imported?
Thanks in advance!
