#- name: set right on /usr/sbin/msmtp
#  file:
#      path: /usr/sbin/msmtp # required. Path to the file being managed.
#      group: mail # not required. Name of the group that should own the file/directory, as would be fed to I(chown).
#      mode: 2711 # not required. Mode the file or directory should be. For those used to I(/usr/bin/chmod) remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like C(0644) or C(01777)) or quote it (like C('644') or C('1777')) so Ansible receives a string and can do its own conversion from string into number.  Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of version 1.8, the mode may be specified as a symbolic mode (for example, C(u+rwx) or C(u=rw,g=r,o=r)).
#      owner: root # not required. Name of the user that should own the file/directory, as would be fed to I(chown).
