首先，微软文档建议这些细节用于 Outlook 的 SMTP。我将其与其他服务配合使用效果很好。
- SMTP 服务器名称：smtp-mail.outlook.com
- SMTP 端口：587
- SMTP 加密：启动TLS
此外，NTFY 建议支持 SMTP 和 STARTTLS。
“截至今天，仅支持具有 PLAIN auth 和 STARTLS 的 SMTP 服务器。”
但是，当我尝试通过文件进行配置时/etc/ntfy/server.yml，它不起作用。
请注意以下日志中的两个错误：

起初我尝试按照微软文档中描述的方式进行连接：
# /etc/ntfy/server.yml
smtp-sender-addr: "smtp-mail.outlook.com:587"
smtp-sender-from: "[email protected]"
smtp-sender-pass: "cencored"
smtp-sender-user: "[email protected]"
之后，我尝试使用文档中所述的旧版 SMTP 端点这里。
smtp-sender-addr: "smtp-legacy.office365.com:587"
无论哪种情况，它都会失败并出现错误。
