# ========================================
#  QE configuration of SMTP notifications
# ========================================
#
# Overview of the configuration this playbook sets up:
#
# * postfix smtp server runs on usm_client machine, listening on public
#   interface
# * tendrl notifier is configured to send email via postfix smtp server running
#   on usm_client directly (so no MX entries are required for this to work)
# * tendrl notifier sends email alerts for admin user to root at
#   usm_client machine
# * root user on client machine can read email alerts for tendrl admin user,
#   which are delevered to his mailbox, via email clients such as mailx or mutt
#
