MozBackup is not available for Mac but there is one alternative that runs on macOS with similar functionality. The best Mac alternative is Mail Backup X, which is free. If that doesn't work for you, our users have ranked four alternatives to MozBackup, but unfortunately only one of them is available for Mac. If you can't find an alternative you can try to remove all filters.
Your one stop mail backup and archiving tool for Mac. Automatically backup mails from Apple Mail, Outlook for Mac, Office 365 for Mac, Thunderbird, Postbox, Gmail, Yahoo and other mail services supporting IMAP and POP service directly on your Mac.
The tool backs up every MAC mail client quite efficiently. It carries a Universal Mail viewer, thus lets me view my old PST files without them being converted to mac outlook.
