自建sentry后，配置了邮件服务，但是还是收不到验证邮件？

问题描述

我已经在config.yml中配置了邮件服务器

mail.backend: 'smtp'  # Use dummy if you want to disable email entirely
mail.host: 'smtp.exmail.qq.com'
mail.port: 587
mail.username: '×××××××'
mail.password: '×××××××'
mail.use-tls: true
# The email address to send on behalf of
mail.from: '××××××'

而且发送测试邮件，我也收到了

但是我在验证邮件部分，却一直收不到邮件

是我什么地方还没有配置吗？
看了一下smtp service的log
