如果得到其他信息如:
Could not open connection to the host, on port 25: Connection failed
其他信息,则可以说明对方邮件服务存在故障,如服务器当机,相关服务没有启动等。导致邮件发送失败。
假设现在不存在该故障,我们获得了220信息。我们将进一步检测故障。
注意:
1.Microsoft Telnet 不允许您使用 Backspace 键。如果在键入时出错,必须按 Enter 键,然后开始键入新的命令。
2.有些 Telnet 应用程序要求您打开本地回显功能,以查看键入的命令。要在 Microsoft Telnet 会话中执行此操作,请在命令提示符处键入 set local_echo。
在 Microsoft Windows XP 中,应键入 set localecho 而不是 set local_echo。
3.提示:500 Command not recognized
检查该命令并再次键入它,或者验证您是否正在与 Microsoft SMTP 服务器直接通信。
请按照我的说明观察以下步骤,红色字体为我敲入的命令。黑色部分为显示结果,中括号中是我写的说明:
