 --syncinternaldates
The source IMAP server stores an INTERNALDATE on each message. When the program adds the message to the destination IMAP server, it specifies the desired INTERNALDATE in the APPEND command it uses to add the message to the target folder. If this is successfult, your migrated mailbox will contain messages with various dates; if it fails, your migrated mailbox will contain messages all dated today. |
