1. 如何查看linux的mailqueue

$mailq

$sendmail -bp

$ll /var/spool/mqueue  这是mail队列存放的目录，可以将里面的文件删除来清空mailqueue

可以通过这些命令来查看邮件是否送出

2. 如何发送mail

1)将文件当做电子邮件的内容送出

语法：mail -s “主题”用户名@地址< 文件

例如：

$mail -s "send with content that is a file" sherry@geminimobile.com < install.log

2)传送mail给本系统用户

$mail 用户名

3)编辑邮件内容

$mail sherry@geminimobile

Subject: messge for job  编辑标题后回车

Apple this job. 开始编辑内容，结束后按Ctrl+D退出内容编辑

Cc:     输入cc地址，如果没有可以直接回车将邮件发送出去

注：Ctrl+C可以中断邮件编辑

4)快速发送邮件

$echo “邮件正文” | mail -s 邮件主题 sherry@geminimobile.com

5)发送附件

$uuencode 附件名 显示附件名 | mail -s "subject" sherry@geminimobile.com

注：uuencode是将二进制文件转换为文本文件的过程，转换后的文件可以通过纯文本e-mail进行传输，在接收方对该文件进行uudecode，即将其转换为初始的二进制文件。

6）发送邮件时增加-v选项可以在终端看到邮件服务器的response

[root@tc-40432-5s ~]# mail -v -s "send with content that is a file" sherry@geminimobile.com < install.log

3. 系统收到的mail会保存在/var/spool/mail/用户名 文件夹中

收mail,键入mail就会显示当前用户的前20封mail。可对邮件进行查看删除等操作。键入？可显示所有命令

$mail
