Hey guys, I’m designing a website and i need to send email to a customer.

But when i use Mailer.deliver_later/1 or deliver_now/1 i receive an error.
I don’t know where is the cause of this error.

My config.exs:

config :shopTest, ShopTest.Mailer,
  adapter: Bamboo.SMTPAdapter,
  server: "smtp.gmail.com",
  port: 587,
  username: "****@gmail.com",
  password: "*******",
  tls: :if_available,
  ssl: false,
  retries: 1

and my module Email:

defmodule Email do
  use Bamboo.Phoenix, view: ShopTest.EmailView

  def welcome_text_email(email_address) do
    new_email()
    |> to(email_address)
    |> from("********.com")
    |> subject("Welcome!")
    |> text_body("Welcome to MyApp!")
  end
end

and my mailer.ex

defmodule ShopTest.Mailer do
  use Bamboo.Mailer, otp_app: :shopTest
end

`Thank you for your help guys!

It’s sending but looks like it’s being rejected by the relay service (smtp status 570) for security reasons. I’ve never used the gmail relay, but there might be a policy that requires a certain configuration e.g. the use of SSL

I found a recent’ish article here that goes into a bit more detail about using their service: How to Use the Gmail SMTP Server to Send Emails for Free
