邮箱是工作中非常重要的一个工具,平常我都是使用foxmail软件或者直接登录web来操作邮件,现在我要换种方式使用邮箱.使用邮箱都是通过pop协议收取邮件,使用smtp协议发送邮件,现在我就直接在命令行中来操作一下邮箱.
pop服务器非SSL加密,一般的端口是110,例如:pop3.sina.net 端口:110
telnet pop3.sina.net
使用USER指令,指定邮箱名
USER shihan2@appdev.sinanet.com
使用PASS指令,指定密码
PASS 密码xxx
使用STAT指令,查看邮箱统计,前一个是邮件数,后一个是邮件所占的空间大小
STAT
使用LIST指令,列出邮件列表,前一个是邮件的编号,后一个是该邮件所占的大小
LIST
使用RETR指令,读取邮件详情,RETR 编号,读出来的就是信体内容了
RETR
使用smtp发送邮件
使用如下命令
telnet smtp.sina.cn
ehlo sina.cn
auth login
xxxxxxxxxxxxxxxxxxxx== #base64加密的邮箱
MjAzOTQ0LmNvbQ== #base64加密的密码
mail from:<shihan@appdev.sinanet.com> #发件人
rcpt to:<@qq.com> #收件人
data
To:@qq.com
From:shihan@appdev.sinanet.com
Subject:测试一下telnet发邮件 测试一下telnet发邮件测试一下telnet发邮件 . #这个必须有
