nailgun smtp with google domains

[cipherzzz]

Hey, @algobasket - I have my mail settings all green in nailgun and the logs are telling me that it sent the email, but nothing ever arrives? I am running this on vagrant from my localhost...

make a simple ruby script to send mail for testing

ruby test.rb

[algobasket]

`require 'mail'
require "mail/parsers/content_type_parser"

options = { :address => "smtp.mailgun.org",
:port => 587,
:domain => 'mailgun.org',
:user_name => 'postmaster@peatio.info',
:password => '66d549cd183a29e697b162e01a552fb3-bd350f28-f9ec91b3',
:authentication => 'plain',
:enable_starttls_auto => true }

Mail.defaults do
delivery_method :smtp, options
end

Mail.deliver do
to 'algobasket@gmail.com'
from 'developer@peatio.info'
subject 'testing sendmail'
body 'testing sendmail'
end`

@algobasket - I ran your script with my mailgun creds above and I received the email. I have port 587 open on incoming and outgoing profile for my ec2 instance... Not sure what else to do at this point?
