Thanks for clarifying the non indent tabs talked about.

I could be 100% mistaken since I don't use rtf, but I believe I understand your problem and for the most part it is self inflicted. I provided you a solution which you never acknowledged trying. And yes, having calibre remove all paragraph spacing and insert indents on every paragraph is a giant alteration of a ebook that does come with limitations inherent in calibre.
You could do as Kovid suggested and save the rtf as web paged filtered then convert to mobi making sure you have a neg value under the indent size so calibre doesn't change your indents (see attached).
If you don't want calibre to change your paragraph indents during conversion then quit telling calibre to change your paragraph indents.
