I suppose the python script is being run through cron and rsync
inherits the script's stderr, so cron converts rsync's error messages
to mail?  How to capture the rsync process's stderr is a Python
question, not an rsync one.  Invoking rsync with popen3 should trap
the error messages and give you a stream from which you can read them.
