TASK [Stouts.postfix : Install requirements (Debian)] ******************************************************************************************************************************************************
[DEPRECATION WARNING]: Invoking "apt" only once while using a loop via squash_actions is deprecated. Instead of using a loop to supply multiple items and specifying `name: "{{item}}"`, please use `name:
['postfix', 'ca-certificates', 'mailutils', 'libsasl2-modules']` and remove the loop. This feature will be removed in version 2.11. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.
