I have one of the best Maildir Converter that can be an effective and instant working solution to convert Maildir files into multiple file formats. I want to suggest the MacSonik Maildir Converter is the most required solution for converting Maildir files into different file formats. This utility can Export emails and folders of Maildir and Maildir++ files to Office 365, Gmail, AOL, Hotmail, Yahoo Mail, and Thunderbird. The Preview feature of this Mac Tool shows you the emails before they are converted. Additionally, you can test the software's free demo version to test its functionality and features.
