To ENABLE DAOS on all new mailfiles created on the server, modify the mail85.ntf (TEMPLATE) to have 'Use Domino ATTACHMENT and Object Service' enabled in the advanced properties. When you select the mail85.ntf, it will automatically INCLUDE settings. This setting will not take effect until a database is at ODS 51. To create databases by default as ODS 51, enable the parameter 'Create_R85_Databases=1' in the server's notes.ini FILE. (While you are editing the template, it's a good idea to enable the 'Use LZ1 compression for attachments' property also to save even more space.)
