安装软件 msmtp mutt

apt-get install -y msmtp mutt

我们这里使用 /etc/msmtprc 来设置机器的全局配置,不用管原来的配置文件，用下面的配置文件替换

# Set default values for all following accounts.
defaults
# The SMTP server of the provider.
account  default
host smtp.163.com
from xxx@163.com
auth login
user xxx@163.com
password xxxpassowrd
tls off
syslog on

到这里msmtp 就配置好了，更多详细的配置可以使用 man msmtp 来得到帮助，帮助最后还有配置示例。

配置 mutt

mutt 的配置文件也有 2 个。

~/.muttrc or ~/.mutt/muttrc
    User configuration file.

/etc/Muttrc
    System-wide configuration file.

同样，我们采用全局配置。

set sendmail="/usr/bin/msmtp" #你的msmtp命令路径
set use_from=yes
set realname="xxx@163.com"  #这里设置的是你发件人别名，可以不是邮件地址
set editor="vim"

测试发送邮件

df -h |mutt -s "useage of hd" xxx@163.com

使用客户端收取邮件内容如下：

useage of hd
xxx@163.com
发给 xxx

配置 nagios 的报警邮件也使用 mutt 来发送。在 nagios 的 command.cfg 中将mail 命令替换成 mutt

# ‘notify-host-by-email‘ command definition
define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/mutt -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
        }

# ‘notify-service-by-email‘ command definition
define command{
        command_name    notify-service-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/bin/mutt -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }
