I have just migrating our existing emails to Xeams. User have connected to old mail server with "Import Wizard" and all messages remains "Unread" even though they were already read. I believe IMAP import wizard can properly mark read/unread messages.

BTW, it would be nice to organise GoodMessages by email as well.

Dalibor,

You are correct. The current implementation of the import wizard does not retain the flags. I would not call this is bug but a missing feature. I will add this request in our wish-list DB.

I am not sure if I understand your second question about being able to "organize good messages". Can you give an example? Perhaps a screenshot would be useful.

Forget the second part, my bad.

I am trying to migrate huge amount of e-mails from the old IMAP. Each method with own problems.

I have found github/imapsync/imapsync which works great.
