How can we change from address in mutt

How can I change the from address in mutt?

Mutt is a mail client in Linux. By default the from address of the mail which is sent by muttrc will be the machine hostname. You can change that using the following steps.

1. Login to the server as root.
2. vi /etc/Muttrc
Update the file using the following.
set realname="Dennis Young"
set from="dennis.young@young.com"
set use_from=yes

3.Save the file

This helps to solve the issue.
