If you configure your Google account for extra security to use the 2-step verification, then
postfix won't send out emails anymore and you might notice error messages in the /var/log/mail.log
file
To fix this issue, you need to visit the (Authorizing applications & sites)
page under your Google Account settings. On this page enter the name of the application to be authorized (Postfix) and click on Generate button.
Set the postfix_sasl_password
variable with the password generated by this page.
A simple example that shows how to add some raw config:
---
- hosts: all
roles:
- oefenweb.postfix
vars:
postfix_raw_options:
