I am trying to use the 3rd answer on How can I send an email through the UNIX mailx command? to send an email.
echo "body" | mutt -s "subject" example@example.com -y
However when I do so, I don't get any email sent to me.
Similarly I also tried mailx which was suggested in another answer to the same question:
mailx -s "subjec_of_mail" example@example.com < file_name
This also didn't work. What am I doing wrong? Thanks
