From Prashant Dave by email on 12th April, 2016, and then adapted by Madhu on 28th Dec, 2018. Please find attached template of muttrc file "muttrc_template" and ssmpt file "ssmtp.conf_template". For the template: 1. The muttrc_template should be in the home folder as $HOME/.mutt/muttrc-file and user name and password needs to be mentioned. The color files, etc (except the ssmtp one below) are to be in the $HOME/.mutt/ folder, with the same file-name (since the muttrc-template looks in this folder with that name.) 2. ssmtp.conf_template needs to be copied to /etc/ssmtp/ssmtp.conf gpo user name, password and local computer name to be specified. Install mutt and ssmtp on ubuntu using sudo apt install mutt sudo apt install ssmtp (For MS Windows: use through cygwin, and for Mac, use MacPorts (i.e. DarwinPorts) or Homebrew. Rest of this file is targetted towards usage in GNU/Linux.) For ease, alias mutt to 'mutt -F ~/.mutt/muttrc-template' by adding the following line into all other aliases (like in .bashrc): alias mutt='mutt -F ~/.mutt/muttrc-template' Once these files are copied, mutt will run without any problem. Note: username (of gpo) has to be put in TWO files. password (of gpo) has to be put in TWO files. Thanks and regards, Prashant
