无法在生产中发送电子邮件
Can't send email in production
我正在开发网上商店，在本地一切正常 machine.Client 将商品添加到购物车，输入他的凭据点击 'Make Order' 然后订单确认应该发送到他的电子邮件。它工作正常，即使使用 redis + 芹菜，但自从我将项目部署到服务器 (linode.com) 后，订单确认不起作用。工人接受了任务但从未执行过。我认为这是因为芹菜，我已经决定在没有任务管理器和队列的情况下发送电子邮件。但是没有用。
我在服务器中使用了UFW防火墙：

问题是我用了Linode，linode阻塞了端口，无意中发现
正如我所读到的，GoDaddy 做同样的事情
Need to send mail from your Linode? New Linode accounts have ports 25,
465, and 587 blocked by default. To have these restrictions removed,
please review this guide, then open a Support Ticket after creating
your Linode.
In an effort to fight spam, Linode restricts outbound connections on
ports 25, 465, and 587 on all Linodes for new accounts created after
