A rim scab in your case is a sistered 2 x 10, about 3' long (minimum), centered and installed on the outside of the existing 2 x 10 beam ends. Using the 6 (2 different length) through-bolts that I suggested earlier. I started using rim scabs after observing way too many splintered beam ends and/or posts, caused by inadequate hole clearances to member ends/edges. Many deck builders overhang their decking planks anyway, making the ends flush with a partial-depth trim joist on the outside to provide some visual relief. The notched 2 x 6s you added to your posts are better than nothing, but I think just using 6 x 6s would be preferable.
Are your 2 x 10s pressure treated? They look rather light in color to be treated. Also, have you applied preservative treatment to all of the post ends you've cut or notched? It's required by the IRC, although most AHJ inspectors won't catch it. The notched posts in your pix look "naked" (untreated). I prefer copper napthanate, the dark green stuff you thin with Stoddard solvent, and it eventually turns a nice uniform brown.
