可以，但是就是无法使用 465 端口发送邮件

支持 25端口和 80端口发送邮件，465 端口不能正常使用

They don’t support 587 or 2525?

是的，我向官方提交了一个意见，内容是要求服务商为邮件推送服务提供 587 端口。 [图片]

我已将阿里云邮件推送服务换成了 Brevo，因为我的 Outlook 无法收到邮件，IP 被拒收了……

This could be due to something specific to your ESP, there were recent reports from another ESP causing issues, does aliyun support any other ports for sending?
