centos6+msmtp+mutt實現SMTP發郵件

 下載msmtp或者mpop（和msmtp同樣小巧的郵件軟件，不在這裏寫過程了。）軟件，當前最新版1.4.30
http://jaist.dl.sourceforge.net/project/msmtp/msmtp/1.4.30/msmtp-1.4.30.tar.bz2
一、編譯軟件
tar jxvf msmtp-1.4.30.tar.bz2
cd  msmtp-1.4.30
./configure --prefix=/usr/local/msmtp
make
make install

二、看一下配置文件在哪裏
# /usr/local/msmtp/bin/msmtp --version

三、msmtp的配置文件
mkdir -p  /usr/local/msmtp/etc
touch /usr/local/msmtp/msmtp.log

vi /usr/local/msmtp/etc/msmtprc
輸入如下內容
defaults
logfile /usr/local/msmtp/msmtp.log
account gmail
tls on
host smtp.gmail.com
port 587
from username@gmail.com
tls_certcheck off
auth login
user username@gmail.com
password password
account default : gmail

四、配置mutt
通常系統已經安裝了，若是沒有安裝的話請使用 yum install mutt 安裝
# tail -5 /etc/Muttrc
#vi /etc/Muttrc.local

set sendmail="/usr/local/msmtp/bin/msmtp"
set realname="測試服務器"
set use_from="yes"
set charset="UTF-8"
set editor="vi"

五、測試一下發送郵件
#echo "測試郵件內容" | mutt -s "測試郵件主題" username@domain.com
tail -f /usr/local/msmtp/msmtp.log 看看有沒有成功，或者進入上面的郵箱看看是否收到郵件。
