When I send email via the 'sendmail' command, the email sent shows 'email@example.com' as the From Address. This is ok, but I have a user that would like it to display their name or something like 'firstname.lastname@example.org User Name' or 'email@example.com My Company Name'.
What would I need to do to have the From address display differently than just the email address?
Note: below is the command that is currently being used, and the 'User Name" does not display just the email address in the From address.
!sendmail -t -F"User Name" -firstname.lastname@example.org < /tmp/tmpwork/mail.1566741834
