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 110

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 1

使用smtp发送邮件

使用如下命令

telnet smtp.sina.cn 25
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:<630892807@qq.com>  #收件人
data
To:630892807@qq.com
From:shihan@appdev.sinanet.com
