You should not need to trace rewriting and calls with verbose logging for something like this. What you should do was mentioned in the welcome message: "TO REPORT A PROBLEM, please see http://www.postfix.org/DEBUG_README#mail"; Namely post 'postconf -n', a non-verbose transaction in question, and results using 'postmap -q' (man postmap for details). Mail loops occur when Postfix detects that it is talking to itself.
