Provision for SMTP

[slick2]

make a provision for smtp, you can choose any posix, ssmtp, sendmail but I think the best would fit would be ssmtp since it's just need outgoing.

please contact me regarding the info of the external smtp details that we would use.

Will use Mailhog as our SMTP server in our vagrant ansible (for Red-hat and debian-based linux systems). link for the ansible role of mailhog: https://github.com/geerlingguy/ansible-role-mailhog
