imap-backup copy SOURCE_EMAIL DESTINATION_EMAIL

This command makes a local copy of the emails in the source account and then copies them to the destination account.

Exactly which folders are backed up (and copied) depends on how the account is set up.

Specifically, the folder inclusion mode (whitelist/blacklist) and folders to include/exclude list.

Note that, any messages on the destination account that is not on the source account are left unchanged.

Options

• --source-delimiter - the separator between the elements of folders names on the source server, defaults to /,
• --source-prefix - optionally, a prefix element to remove from the name of source folders,
• --destination-delimiter - the separator between the elements of folder names on the destination server, defaults to /,
• --destination-prefix - optionally, a prefix element to add before names on the destination server,
• --automatic-namespaces - works out the 4 parameters above by querying the source and destination IMAP servers.
