Ansible role: Postfix

Install and configure postfix on an Ubuntu or Redhat server.

Primarily for use in hosting environments so a website can deliver mail via 127.0.0.1.

Requirements

• Redhat or Ubuntu

• Your playbook must gather_facts

Role Variables

• default_mail_recipient: The email address of the person who should receive mail for root (stuff that was generated by the server; ie cron failure notifications)

For servers that accept incoming mail:

• postfix_tls_cert: Absolute path to the TLS public certificate
• postfix_tls_key: Absolute path to the TLS private key

For systems behind a load balancer:

• postfix_myhostname: In some cases, ansible won't be able to figure out what to use for this, so you'll need to specify it manually

Tweaks: These only get applied if your playbook specifies them. Otherwise, the defaults for these are left up to your OS.

• postfix_inet_interfaces: Defaults to "all" on debian, and "localhost" on red hat.

• postfix_mynetworks: Default for both OS's is only to trust localhost.

• Set 'enable_resolv_conf_watcher' to 'true' if postfix is having issues with resolving DNS.

Dependencies
