Ruby on Rails + Gmail SMTP (TLS)

This took way too long to figure out the answer to without using a custom plugin. I hope this helps others! I was setting up Redmine with Gmail as an SMTP server utilizing config/email.yml. Behold!

email.yml with no other related changes in environment.yml using Rails 2.2.2


delivery_method: :smtp
enable_starttls_auto: :true
port: 587
authentication: :plain
tls: :true
user_name: ""
password: "YOURPASS"

If you are setting up Redmine, there is a nice feature under Administration > Settings > Email Notifications > and in the very bottom right corner of the page, a “Send a Test Email” link.
