我无法从smtp-mail.outlook.com
ufw并且防病毒软件已被禁用：
Sending of the message failed.
The message could not be sent because connecting to Outgoing server (SMTP) smtp-mail.outlook.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.
此错误仅出现在基于 Linux 的机器上，Windows 和 Mac 上不存在错误：
telnet smtp-mail.outlook.com 587
Trying 98.124.245.24...
telnet: Unable to connect to remote host: Connection refused
还：
telnet smtp-mail.outlook.com 25
Trying 98.124.245.24...
telnet: Unable to connect to remote host: Connection refused
并且ping 98.124.245.24有效
可能是什么问题呢？
答案1
解析的地址似乎是问题所在，98.124.245.24对我来说也不起作用。但是telnet 40.100.29.34 587工作正常。40.100.29.34是我机器上的 IP 地址解析smtp-mail.outlook.com。您还应该检查 Mac 上服务器的解析 IP。
