Hi all! I am planning to migrate about 200 e-mail accounts from a mail server using Dovecot to a mail server running Cyrus.
The idea is to migrate emails maintaining the status read, unread, etc, and also synchronize Draft, Sent and Trash folders in each mailbox. I think the best will be make it through IMAP. This would also be agnostic to the storage mechanism used (MAILDIR, system users accounts, etc) in the source and destination servers. Following this course of action, I found this  interesting article written by Falko Timme in HowtoForge. But it seems that imapsync is no longer available in the Debian repositories  because the developer was implementing a payment model for obtaining this software and then maybe he thought that Debian could affect their income so he gave a resounding "No"  to continue distributing it. A very respectable decision, I think. I was checking the official site  of imapsync and even though the developer seems to have a paid business model, it seems that the source code is still available. In fact he has documented the Debian installation process  and there he makes mention of downloading a tarball. Although I do not see a link on where to get the tarball. Maybe I'm missing something? It seems that the license  has no restrictions, but it is unclear where to get the code (again, if I'm missing something, please let me know). Apparently there is a repository on Github for imapsync  but I have come to it using a search engine. For the current license, this could make it a candidate for incorporation in the Debian repositories again? Thanks in advance.
