Devopera puppet module for setting up the Postfix mail relay agent, which is a fast, easy to administer and secure alternative to Sendmail.



  • Added SELinux cover for non-standard relay ports (e.g. 2525 instead of 25)


  • Added relay support and authenticated relay support


Null sender setup

class { 'dopostfix' : }

Relay setup to named host on named port

class { 'dopostfix' :
  relay => true,
  smtp_auth => true,
  smtp_hostname => '',
  smtp_username => 'username',
  smtp_password => 'password_or_API_key',

dopostfix will send mail out via the domain's mail server, found from the FQDN using its MX record unless:

  1. force_restrict_relay => true, or
  2. FQDN finishes .localdomain, or
  3. relayhost != undef
