[REVIEW] 398 - Fix unavailable local smtp envs

[WelisonR]

Description

Accordingly to #398, local smtp local variables is not being defined by docker-compose.yml. So, it solves this problem and, furthermore, include all SMTP variables to envs (server, port, email, password).

How to test: to test this pull request, you will need to use a SMTP server. You can use a gmail account (I recommend to create a test account), change the Less secure app access and fill the .smtp file.
