Flask-Mail [111]连接被拒绝

Question

一切正常。我正在运行Ubuntu 16.04，已禁用防火墙，已激活Gmail上的“允许不安全的应用程序”设置，在配置后放置mail = Mail(app)。

MAIL_SERVER= 'smtp.googlemail.com'
MAIL_PORT=587
MAIL_USE_TLS=1
MAIL_USERNAME='newlycreatedemail@gmail.com'
MAIL_PASSWORD='newlycreatedemailpawword'
ADMINS=['newlycreatedemail@gmail.com']

mail = Mail(app)

发送方功能：

@app.route('/confirmemail/',methods=['POST','GET'])
def confirmEmail():
    user = User.query.filter_by(username = session['username']).first()
    form = EmailForm()
    if request.method == 'POST' and form.email.data == form.confirmEmail.data:
        sendEmail('Confirm your email!',
            sender=ADMINS[0],
            recipients=form.email.data,
            text_body="Merge!",
            html_body="Merge html")
        return render_template('emailconfirm.html',form=form)
    else:
        return render_template('sendconfirmationemail.html',form=form)
