{Check Install Start sendmail }

//Install
yum install sendmail

//Check
ps -ef | grep sendmail

//Start
service sendmail start

chkconfig --level 2345 sendmail on

{ Check and Install mutt }

//check mutt install, if already installed, will return /usr/bin/mutt
# which mutt

//install mutt
# yum install mutt

{ Config mutt }

Have 2 config way:

1. config global mutt, direct edit /etc/Muttrc 
2. config for user level mutt, copy /etc/Muttrc to /curUser/.muttrc

//copy for root user
# cp /etc/Muttrc /root/.muttrc

for above two way, have same config steps

#encode
set charset="utf-8" 

#custom from info
set envelope_from=yes #if not found this one, direct add it manual
set use_from=yes 
set from=yiilib.com@gmail.com
set realname="Master Lee"
