profile_email

Enable email via postfix.

relayhost

Options:

• outbound-relays.ncsa.illinois.edu (default)
  • Useful for hosts in NCSA Private IP space (172.24.0.0/13).
• outbound-relays.techservices.illinois.edu
  • Recommended for hosts in NCSA Public IP space (141.142.0.0/16)
    • Note: must also have a public hostname (e.g. *.illinois.edu) and that hostname must be set in myhostname and myorigin. The default settings work fine for the most common case when a node has just one hostname and one IP, but more care is needed when a node has more than one.

root_mail_target

The default root email address is devnull@ncsa.illinois.edu. devnull@ncsa.illinois.edu is an actual mail alias setup on NCSA’s pop server that just drops the message. This will have to be changed via hiera data in order to have root mail sent to the appropriate place.

Email relay

To optionally support usage as an SMTP relay, you need to specify inet_interfaces & mynetworks parameters to know where to listen and relay from:

profile_email::inet_interfaces:
  - "172.0.0.2"     # IP OF LOCAL INTERFACE TO LISTEN ON
profile_email::mynetworks:
  - "172.0.0.0/24"  # SUBNET TO ALLOW RELAYING
profile_email::smtpd_tls_security_level: "none"
