Ansible role for configuring Mailgun SMTP relaying with Postfix

Howdy! 🤠

ansible-mailgun's Issues

SASL package needed on Debian Jessie

On Debian Jessie, this role will product the following errors in the mail log when sending emails:

warning: SASL authentication failure: No worthy mechs found
delivery temporarily suspended: SASL authentication failed; cannot authenticate to server smtp.mailgun.org[23.22.131.222]: no mechanism available

This is due to the lack of the relevant sasl2 modules for secure connection to mailgun. To fix manually:

apt-get install libsasl2-modules
/etc/init.d/postfix restart

Or in Ansible after the Mailgun role:

- name: Install SASL modules for Mailgun (bug workaround)
  hosts: aws:offsite:legacy
  become: true
  tasks:
    - apt: name=libsasl2-modules state=present
    - service: name=postfix state=restarted

No package matching 'postfix_packages' is available

Ansible 2.2.0.0

Executing this role gives this error:

failed: [server1] (item=[u'postfix_packages']) => {"failed": true, "item": ["postfix_packages"], "msg": "No package matching 'postfix_packages' is available"}

Ansible 2.2.0.0 depreciation removal list:

with_ 'bare variable' handling, now loop items must always be templated {{ }} or they will be considered as plain strings.
skipping task on 'missing attribute' in loop variable, now in a loop an undefined attribute will return an error instead of skipping the task.
skipping on undefined variables in loop, now loops will have to define a variable or use |default to avoid errors.

Need to change

with_items: postfix_packages

to

with_items: "{{postfix_packages}}"

in /tasks/debian.yml

add smtp server in variables to be able to manage EU region

Hello

Thank you for your job!
The configuration does not work when using Mailgun EU servers because the smtp server is smtp.eu.mailgun.org.

At this time in mailgun.conf.j2 you have : relayhost = [smtp.mailgun.org]:587

Could you please add this in a variable with default value smtp.mailgun.org so we would be able to define our own variable if needed to setup for example smtp.eu.mailgun.org.
If you prefer you can use another solution to set directly the right server, it is up to you. For example by adding in the configuration the region...

At this time there is only two regions used by Mailgun : US and UE.

Thank you :)

Invoking package manager only once while using a loop via squash_actions is deprecated.
