Setting up msmtp SMTP client

a)
Install msmtp
sudo apt-get install msmtp
touch ~/.msmtprc ~/.msmtp.log
chmod 600 ~/.msmtprc ~/.msmtp.log

b)
Add following lines in ~/.msmtprc
----------------------------------

defaults
logfile ~/.msmtp.log

account default
host localhost
port 1025
protocol smtp
from saju.madhavan@myorg.com
#auth on
user IN\saju.madhavan
password mypassword

#auto_from off
#tls off

#tls on
#tls_starttls on
#tls_certcheck off
auth login

3)
Setting up mutt for email
==============================

a)
Add following lines in ~/.muttrc

set folder="imap://saju.madhavan:mypassword@127.0.0.1:1143"
set from="saju.madhavan@myorg.com"

set trash="imap://saju.madhavan:mypassword@127.0.0.1:1143/Trash"

set imap_pass="mypassword"
set imap_keepalive=900   # Set lower if connection times out
set header_cache=~/.mutt/cache/headers
