So I'd probably debug by adding logging. Specifically something like this:
print >> sys.stderr, "WSGIHandler called to handle request;
environ=%r" % environ
to django/core/handlers/wsgi.py as the first line in the __call__ method for
WSGIHandler. Each resulting entry you see in the Apache error log indicates
Django was called by Apache to handle a request, and the PATH_INFO key in
the environ will show what the request is for, exactly.
Similarly add logging to where you send the email. Issue your single
request and check the access and error logs for where the duplication is
happening.
If you get multiple email send logs for a single WSGIHandler __call__ then
it's resulting from within Django or your code, and you can head down the
path of logging the call stack at the email send point, or adding more
logging along the execution path, to figure out what's going on.
If you get multiple WSGIHandler __call__ logs for a single entry in access
log, then it's something outside of Django that is causing the problem. I
have no idea how that would be happening.
If you get a single WSGIHandler __call__ log and a single email send log,
but multiple emails, then something is duplicating the sent emails, or there
is somewhere else in your code sending emails.
