Hello,
recently tried to make a fresh install of Gitlab CE with SMTP enabled.
content of corresponding group_vars/gitlab.yml:

gitlab_external_url: "https://git.example.com"
gitlab_redirect_http_to_https: "true"
gitlab_create_self_signed_cert: "false"
gitlab_smtp_enable: "true"
gitlab_smtp_address: "smtp.example.com"
gitlab_smtp_user_name: "[e-mail]"
gitlab_smtp_password: "g)^fJZ<^kE$HAAh<3:$'KBVbt=Zcwv{>"
gitlab_smtp_domain: "example.com"
gitlab_email_enabled: "true"
gitlab_email_from: "gitlab@example"
gitlab_email_display_name: "Gitlab Example"
gitlab_email_reply_to: "[e-mail]"

Found answer myself at https://docs.gitlab.com/omnibus/settings/smtp.html

Warning: Your smtp_password should not contain any String delimiters used in Ruby or YAML (f.e. ') to avoid unexpected behavior during the processing of config settings.
