1. 部署在heroku后，注册用户时无法发送邮件，本地测试时没有问题。

2. 本地测试是在虚拟环境下测试，没模拟部署环境测试

3. google后看到的前几个大多是因为用了gmail的原因，我用的是网易邮箱。

返回以上错误时smtp的配置是MAIL_PORT = 25，MAIL_USE_TLS = True

相关代码email.py

from threading import Thread from flask import current_app, render_template from flask_mail import Message from . import mail def send_async_email(app, msg): with app.app_context(): mail.send(msg) def send_email(to, subject, template, **kwargs): app = current_app._get_current_object() msg = Message(app.config['FLASKY_MAIL_SUBJECT_PREFIX'] + ' ' + subject, sender=app.config['FLASKY_MAIL_SENDER'], recipients=[to]) msg.body = render_template(template + '.txt', **kwargs) msg.html = render_template(template + '.html', **kwargs) thr = Thread(target=send_async_email, args=[app, msg]) thr.start() return thr 从哪里分析呢？可能是哪出了问题呢？

这还有个解决办法不过代码我没有看懂。

---

stmp配置：

class Config: SECRET_KEY = os.environ.get('SECRET_KEY') or 'hard to guess string' SSL_DISABLE = False MAIL_SERVER = 'smtp.163.com' MAIL_PORT = 465 MAIL_USE_SSL = True MAIL_USERNAME = os.environ.get('MAIL_USERNAME') MAIL_PASSWORD = os.environ.get('MAIL_PASSWORD') FLASKY_MAIL_SUBJECT_PREFIX = '[oFlasky]' FLASKY_MAIL_SENDER = 'b1a2b3c4d@163.com' FLASKY_ADMIN = os.environ.get('FLASKY_ADMIN')

前一次配置文件中的MAIL_USE_SSL没有配置，而是使用的TLS，MAIL_PORT 也是按照网易官网写的25。今天改成以上的配置了，还是返回错误：
