Configuration is ignored, mail is sent with default ActionMailer settings about spree_mail_settings

+1 I'm running into the same issue

I have Mailgun configured as an external SMTP and when I click "send test e-mail" it says:
Test Mail error: Connection refused - connect(2) for "localhost" port 25

Getting the same error at completion of checkout, basically unable to send e-mails as Spree is not using the config provided via this gem

I'm just taking a look at the code now but seems to me that instead of just using the default Spree mailer (such as Spree::TestMailer) it will be necessary to override the class (via a decorator?) and use the SMTP parameters provided via the settings.

Similar to this example from the Rails docs:

class UserMailer < ApplicationMailer
def welcome_email(user, company)
@user = user
@url = user_url(@user)
delivery_options = { user_name: company.smtp_user,
password: company.smtp_password,
address: company.smtp_host }
mail(to: @user.email,
subject: "Please see the Terms and Conditions attached",
delivery_method_options: delivery_options)
end
end
