Missing server option

Hi to all. In order to try to send an email with external image linked I went in the configuration settings document on the server, as suggested in the Administrator 6.5 help,in the “MIME - Conversion Options - Outbound” tab.

Help says to set the “Message Content” field to “Convert from Notes to HTML” or “Convert from Notes to Plain Text and HTML”, but I can found only “Convert form Notes to the internet message format” and “Convert Multi-part alternative including conversion and encapsulation” options.

How could I set the right configuration option in my Domino 6.5 server in order to convert email in the right way ? ? ?

Thank you in advance.
