Django not logging all errors on production - django

Question

My Django app is only properly logging and emailing errors when Debug=True.
On production, I'm only getting 'Invalid HTTP_HOST header' errors in both the log file and my inbox. Every other error is not logged in the django log nor is it emailed to me.
I've tried some things with this test request:
def test(request):
logging.debug('debug test message') // Always appears in log file
from django.core.mail import mail_admins
mail_admins('test error', 'test error via call to mail_admins()') // Always arrives in my inbox just fine
raise Appointment.DoesNotExist // When Debug=False (both locally and in production), does not appear in log file or in inbox.
My logging settings for both local and production:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(message)s'
},
'csv_formatter': {
'format': '%(levelname)s;%(asctime)s;%(message)s'
}
},
'handlers': {
'null': {
'level': 'DEBUG',
'class': 'logging.NullHandler',
},
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'verbose'
},
'default': {
'level': 'DEBUG',
'class': 'logging.handlers.RotatingFileHandler',
'maxBytes': 1024 * 1024 * 50,
'backupCount': 10,
'formatter': 'csv_formatter',
},
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler',
'formatter': 'verbose',
},
},
'loggers': {
'': {
'handlers': ['default'],
'level': 'DEBUG',
'propagate': True,
},
'asyncio': {
'level': 'WARNING',
},
'django.request': {
'handlers': ['mail_admins'],
'level': 'ERROR',
'propagate': True,
},
'django.security': {
'handlers': ['mail_admins'],
'level': 'ERROR',
'propagate': True,
},
}
}
How do I make sure all Django errors are logged and emailed in production (when Debug=False)?
