使用cpanel python应用程序不会发送电子邮件

由于NGINX服务器上的域问题，我正在尝试将cpanel python应用程序用于我的python应用程序

我已经安装了python应用程序，并安装了运行该应用程序的所有模块。应用程序运行正常，但在联系人页面上，当我尝试发送联系人表单信息时，我收到一个500内部服务器错误

代码在NGINX服务器上运行得非常好。为了让代码在cpanel中的python应用程序上运行，我确实需要做一些更改，但它只是main.py文件中的passenger_wsgi.py文件和app.run文件

下面是我的app.py（主python文件）代码

这是form.py代码

from flask_wtf import Form
from wtforms import StringField, TextAreaField, SubmitField
from wtforms.validators import DataRequired, Email


class ContactForm(Form):
    full_name = StringField('Name', validators=[DataRequired('Please add your name')])
    email = StringField('Email',
                        validators=[DataRequired('Please enter your email'), Email('Please enter a valid email')])
    subject = StringField('Subject', validators=[DataRequired('Please enter the subject of this email')])
    company = StringField('Company', validators=[DataRequired('Please enter your company name')])
    message = TextAreaField('message', validators=[DataRequired('Please enter a message')])
    submit = SubmitField("Send")

这是“联系我们”页面上的表格

我将电子邮件和密码更改为示例。没有错误日志或代码，仅在单击“发送”按钮后显示500个内部服务器错误。除此之外，该应用程序的其他所有内容都可以很好地加载

如果有关于这个问题的任何文档，那就太好了。我已经在谷歌上搜索了大约4天，现在找不到任何关于这个问题或如何让它工作的可靠信息。

设法解决了这个问题，Cpanel不允许用户form.email.data作为发件人。所以我不得不把它改成实际的发件人电子邮件info@example.com. 我添加了一个回复，这样你就可以回复客户了

我还必须改变配置

app.config["SECRET_KEY"] = "Long Secret Key"
app.config["MAIL_SERVER"] = "mail.example.com"
app.config["MAIL_PORT"] = 25
app.config["MAIL_USE_SSL"] = False
app.config["MAIL_USERNAME"] = 'info@example.com'
app.config["MAIL_PASSWORD"] = 'password'

@app.route('/contact_us', methods=['GET', 'POST'])
def contact_us():
    form = ContactForm()

    if request.method == 'POST':
        msg = Message(form.subject.data, sender=("Contact Form", "info@example.com"), recipients=['info@example.com'], reply_to=form.email.data)
        msg.body = """
              From: %s
              Email: %s
              Company Name: %s
              Message: %s
              """ % (form.full_name.data, form.email.data, form.company.data, form.message.data)
        mail.send(msg)

        return render_template('contact_us.jinja2', success=True, form=form)

    elif request.method == 'GET':
        return render_template('contact_us.jinja2', form=form)

添加回溯

app.config["SECRET_KEY"] = "Long Secret Key"

app.config["MAIL_PORT"] = 25
app.config["MAIL_USE_SSL"] = False

app.config["MAIL_PASSWORD"] = 'password'

@app.route('/contact_us', methods=['GET', 'POST'])
def contact_us():
    form = ContactForm()

    if request.method == 'POST':
        msg = Message(form.subject.data, sender=("Contact Form", "info@example.com"), recipients=['info@example.com'], reply_to=form.email.data)
        msg.body = """
              From: %s
              Email: %s
              Company Name: %s

              """ % (form.full_name.data, form.email.data, form.company.data, form.message.data)
        mail.send(msg)

        return render_template('contact_us.jinja2', success=True, form=form)
