Telnet telnet 192.168.193.138 25
如果正常，您将会看到以下来自 IMC 的响应：
220 matchdu.cn Esmtp
键入以下命令开始进行通讯：
EHLO root@bj-oms-email1.localdomain
EHLO root@sz-oms-email.localdomain
EHLO root@en-oms-email.localdomain
您应看到如下响应：
250 OK
键入以下命令来通知 IMC 邮件源于何处：
MAIL FROM: root@en-oms-email.localdomain
按 ENTER 您应得到如下响应：
250 OK
键入以下命令来通知 IMC 邮件的目标地址。
RCPT TO: a591244761@163.com
RCPT TO: lvyingxin@huawei.com
按 ENTER 您应看到如下响应：
250 OK
键入以下命令以通知 IMC 您已准备好发送数据：
DATA
按 ENTER 键您应看到如下响应：
354 Send data.
键入以下命令以添加主题行：
Subject: test message
然后按两次 Enter 键。
该命令看不到任何响应。
备注：两个 Enter 命令符合 RFC 822 规则，即 822 命令后必须跟空行。
键入以下命令来添加邮件正文：
This is a test message
i love you
.
您将看不到来自该命令的响应。
在紧接着的空行处键入句号，然后按 ENTER 键。
您应看到如下响应：
250 OK
注意有的 smtp 服务器是需要验证
pop3
telnet xxx.xxx.xxx.xxx 110
user **
+ok
pass **
+ok
list

acpt 1 (查询邮件)
RETR 1 (查询邮件)
quit
SMTP 命令包括：
我们通过 telnet 到邮件服务器 25 端口后, 就可以使用以下的命令来发送邮件了.
HELO 向服务器标识用户身份。发送者能进行欺骗，但一般情况下服务器都能检测到。
EHLO 向服务器标识用户身份。发送者能进行欺骗，但一般情况下服务器都能检测到。
MAIL FROM 命令中指定的地址是发件人地址
RCPT TO 标识单个的邮件接收人；可有多个 RCPT TO；常在 MAIL 命令后面。
DATA 在单个或多个 RCPT 命令后，表示所有的邮件接收人已标识，并初始化数据传输，以 CRLF.CRLF 结束
VRFY 用于验证指定的用户 / 邮箱是否存在；由于安全方面的原因，服务器常禁止此命令
EXPN 验证给定的邮箱列表是否存在，扩充邮箱列表，也常被禁用
HELP 查询服务器支持什么命令
NOOP 无操作，服务器响应 250 OK
RSET 重置会话，当前传输被取消，服务器响应 250 OK
QUIT 结束会话
