The tool supports IMAP mailboxes from Gmail, Yahoo, Outlook.com, G Suite, Amazon WorkMail, AOL, etc. You can add single or multiple IMAP mailboxes for the backup as you want. And moving forward, you can apply filters to customize your backup, like you can select the required folders from the mailboxes you want to create backup. Also, you can provide a date range to back up emails of a specific period, exclude deleted folders or empty folders, skip already migrated emails, and can opt for saving the entire hierarchy to a new folder. The tool provides you an option to set a timeout period to skip the items that may take more than usual time.
