How to solve the problem with sending an email in django in production?

Question

Django

Good afternoon. Required behavior: an order is formed on the site, after placing the order it goes to the admin panel and is sent to the mail of the site owner. This behavior works correctly from under the Dzhang server, but does not want to send it from production.
Actually the piece of the view itself

def send_order_to_crm(order):
    data = {
        "client": {
            "name": order.client.name,
            "phone": order.client.phone,
            "email": order.client.email
        },
        "info": {
            "total": order.sum,
            "created": order.created.strftime("%d.%m.%Y %H:%M")
        },
        "orders": [

        ]
    }

    for op in order.order_products.all():
        data["orders"].append(
            {
                "name": op.product.title,
                "description": op.product.desc,
                "count": op.count,
                "cost": op.product.cost,
                "sum": op.sum,
            }
        )
    print data

    headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
    r = requests.post('http://crm.goeasyy.ru/api/v1/orders',
                      data=json.dumps(data),
                      headers=headers)
    print r.text
    return False

What else to add to fully understand the possible reasons for this, in my opinion, strange behavior?

Answer 1

Why do you print to the console in production?
Output to the log at least.
Comment out or remove the lines with print - the error will disappear.
