Asking about the status of paper you refereed?

I refereed a paper after a skim-through and a careful examination of about (1/3) of it after a couple of weeks, and then sent it back due to expository issues, a few gripes about certain things not being correct, about a dozen notes, and suggestions on what needs cleaning so that I could rigorously go through all the arguments to check everything and give a better assessment of the paper. I gave it a gut feeling of about what level of quality the paper seemed to be, relating it to another paper in the close literature. In the report, I said I would be happy to referee the paper more fully after these preliminary edits are made.

Almost a month has gone by and the editor has not acknowledged my emailing of the referee report to him. Do I wait to see if he acknowledges my report or does this get stuck in the ether without me knowing the result of the paper? Do I email him asking if he received my referee report? Was I wrong in sending it back to the authors so quickly to ask for more clarity? Or should I be taking a back seat to this and only responding when prompted and going along my merry way?
