Anonymous FTP access allows anyone to access your public_ftp folder. There are two options available:

• Allow anonymous access to ftp://ftp.yourdomain.com - This allows to view, download, and delete files from your public_ftp folder.
• Allow anonymous upload to ftp://ftp.yourdomain.com/incoming - This allows to view, upload, download, and delete files from your public_ftp/incoming folder.
