New Ansible Role uploaded to Ansible Galaxy

Reading time: 2 – 2 minutes

A long time ago I wrote an entry post about how to set up the SMTP in linux boxes using a relay system you can find the post here: Relay mail from your server without MTA. Remember that SSMTP is not a SMTP service for your system but it’s more than enough for all servers that don’t work as a mail servers. Historically Unix/Linux uses sendmail command to send system notifications but usually this mails are lost because system configurations are not completed. My advice in this sense is use SSMTP.

In the past I used to use SSMTP with a GMail account but security constraints in Google mail services make it difficult to configure today. The new alternative is set up a free Mandrill account as a relay host. Mandrill is a Mailchimp service that allows you to send a lot of emails without problems and there is a free account that allows to send up to 12.000 mails per month free, more than enough usually. If you don’t know how to set up a Mailchimp account the best option to learn how to do it is follow the support documentation it’s very good IMHO.

When you have a lot of linux machines to administer you need something fastly replicable. As you know use Ansible is a very good option. Then I developed a new Ansible role to set up Mandrill accounts to SSMTP services massively using Ansible.

The Ansible role has been uploaded here: ssmtp-mandrill and the source code of the roles is in my github. Remember to install the role in your Ansible is easy:

ansible-galaxy install oriol.rius.ssmtp-mandrill

Then you only need to create your own playbook using the role and don’t forget to setup the variables with the Mandrill account settings.

Relay mail from your server without MTA

Reading time: < 1 minute Sometime you need to send notifications or simply you need to use sendmail command from your server, but you don't want to use a local mail server. Maybe use simple SMTP (ssmtp) could be a good idea to solve this kind of situations. I use to configure SSMTP with a GMail account to send notifications from server different daemons, for example, crontab, supervisord, etc. This is a cookbook configuration for SSMTP and GMail: /etc/ssmtp/ssmtp.conf



Installation in ubuntu server is as easy as: apt-get install ssmtp
