Help setup email verification in Phoenix

I noticed the default email verifaction set by gen.auth is to save email localy, So I tried using SMTP but I have been facing some issues, I was able to fix it up to some point, but am not sure I know what’s really wrong again

here is there error log

[error] GenServer #PID<0.1077.0> terminating

Am using Google smtp, The Config seems very fine to me and the Swoosh.Adapters.SMTP.deliver/2 is also okay, obviously I am missing something, I am new to phoenix , I will really appreciate your help.
Thanks

Hi @Seyi it’s pretty hard to help if you don’t show your code.

Here are the relevant part of the code You might need to see

Config

config :goolify, Goolify.Mailer,
  adapter: Swoosh.Adapters.SMTP,
  relay: "smtp.gmail.com",
  username: "me@mail.com",
  password: "my-mail-password",
  ssl: true,
  tls: :always,
  auth: :always,
  port: 465,
  retries: 2,
  no_mx_lookups: false

userNotifier file

  defp deliver(recipient, subject, body) do
    email =
      new()
      |> to(recipient)
      |> from({"Goolify", "admin@mail.com"})
      |> subject(subject)
      |> text_body(body)

     case Mailer.deliver(email) do
      {:ok, _metadata} ->
        {:ok, email}

      {:error, reason} ->
        {:error, reason}
    end
  end

Hi @Seyi , I fought with SMTP settings yesterday and this changes in config worked for me:

…
ssl: false,
tls: :always,
tls_options: [verify: :verify_none],
auth: :always,
port: 587,
…

I have no idea, why the port is this one (my SMTP provider gave me standard 465) but I tried all combinations and read many questions/answers online.

I believe that TLS will somehow negotiate secure connection. TLS options for verify just tells that you do not want it to verify email server certificate. I think (not sure) that if you would like to do it, you will need to set up some proper certs…

Hope it will work for you, too.

This might help someone: the method above didn’t work for me, maybe because my OTP version is 27. I ended up solving the issue easily using Swoosh’s Mua.
