问题描述：利用Mutt结合Msmtp在运行Linux系统的主机收发邮件。
解决方案：
（一）、 Msmtp安装与配置
1. Linux系统安装Msmtp
1.1 下载msmtp-1.6.6.tar.xz
1.2 运行以下命令进行安装
tar Jvxf msmtp-1.6.6.tar.xz
cd msmtp-1.6.6
./configure
make && make install
2. Linux系统配置Msmtp
2.1 创建.msmtp.log文件
touch ~/.msmtp.log
2.2 创建.msmtprc文件并更改文件权限为600
touch ~/.msmtprc
chmod 600 ~/.msmtprc
2.3 编辑.msmtprc文件为以下内容
defaults
logfile ~/.msmtp.log
# gmail
account Gmail
tls on
auth on
host smtp.gmail.com
port 587
tls_certcheck off
user *** # your username instead of your mail account
password *********
3. Linux系统运行Msmtp
echo "This is a test email from msmtp" | msmtp recipent@domain.com
（二）、Mutt安装与配置
1. Linux系统安装mutt
1.1 Centos系统
yum install mutt
1.2 Arch linux系统
pacman -S mutt
1.3 Ubuntu系统
apt-get install mutt
2. 配置mutt
2.1 创建.~/.muttrc文件，并将以下内容写入.muttrc文件。
set from = "user@gmail.com"
set realname = "username"
set imap_user = "user@gmail.com"
set imap_pass = "password"
set imap_keepalive = 900
set sendmail = "/usr/local/bin/msmtp" #path depends on where you install msmtp, if you don't know try "which msmtp"
set use_from = yes
set envelope_from = yes
set folder = "imaps://imap.gmail.com:993"
set spoolfile = "+INBOX"
set postponed ="+[Gmail]/Drafts"
set header_cache =~/.mutt/cache/headers
set message_cachedir =~/.mutt/cache/bodies
set certificate_file =~/.mutt/certificates
set move = no
set editor = vim
2.2 创建mutt和cache文件夹用于储存信件头和信件正文。
mkdir -p ~/.mutt/cache
3.运行实例
3.1 运行以下命令,对mutt命令进行测试。
echo "Test email" | mutt -s "Test" user@qq.com
3.2 运行mutt在图形用户界面查看来往信件及发送邮件。
