Loving Zimbra! Another question has cropped up. Some of our customers have got large mailboxes on other mail servers and want to migrate/copy all their existing mail to the Zimbra server. Apart from just creating the two mail accounts in Outlook or MacMail and then highlighting the mail they want to move and then move it that way, is there an easier, quicker way to do this? One of the mailboxes has 13,000 messages in it and we've (foolishly) offered to help the customer move the mail, so any help would be sincerely appreciated at this point.
