Sharing the code and error below.

Thanks!

**CODE**
```
imports..

def train_model(X_train,y_train,X_test,y_test):
classifier=SVC()
classifier.fit(X_train,y_train)
return f'Accuracy of the model: {(classifier.score(X_test, y_test))*100}%'

@email_sender(recipient_emails=["bhavishyapandit9@gmail.com"],sender_email="knockknocknotificationstest@gmail.com")
def train_model_email_notify(X_train, y_train, X_test, y_test):
return train_model(X_train,
y_train,
X_test,
y_test)

wines=datasets.load_wine()
x = wines['data']
y = wines['target']

X_train, X_test, y_train, y_test = train_test_split(x,y,test_size=0.2)
mm = MinMaxScaler()
X_train=mm.fit_transform(X_train)
X_test=mm.fit_transform(X_test)
train_model_email_notify(X_train, y_train, X_test, y_test)
```

Start at the email_sender decorator entry point shown in knockknock/email_sender.py, especially wrapper_sender, and reproduce the SMTP connection with the reported Python and macOS environment. Inspect how the sender is configured before yagmail connects; done means identifying whether knockknock causes the reset and documenting or fixing a reproducible project-side cause.
