Trouble sending email over Gmail

[sh4t4d33p]

I have created a basic email sending application. I have tested it locally using the mailbox preview server. However, when I change the configuration to send the email over Gmail, I get errors.

1. When I use port 1025, the error is:- {:error, {:retries_exceeded, {:network_failure, 'smtp.gmail.com', {:error, :timeout}}}}.
2. When I use port 465, I get:- {:error, {:retries_exceeded, {:network_failure, 'smtp.gmail.com', {:error, :closed}}}}.
3. When I use port 587, I get:- {:error, {:no_more_hosts, {:permanent_failure, 'smtp.gmail.com', :auth_failed}}}.

My config.exs looks like this:-
config :my_app, MyApp.Mailer, adapter: Swoosh.Adapters.SMTP, relay: "smtp.gmail.com", username: "some.name@gmail.com", password: "password", tls: :always, auth: :always, port: 587
I enabled access through less secure apps in my Gmail account, but it's still not working. Could somebody tell me what the problem is?

Hello @sh4t4d33p, sorry to hear you're having issues sending email with Swoosh/Gmail.

Do you have two-factor authentication enabled on this account by any chance? If that's the case you will need to generate an app specific password: https://support.google.com/accounts/answer/185833?hl=en

If you mean the 2-step verification which uses the password and a unique verification code, then I don't have it enabled.

@sh4t4d33p I'm assuming this is no longer an issue and closing. Please reopen if that's not the case.

FYI: I am using mailman elixir and maybe same issue with swoosh, using mailman I got

{:error, {:no_more_hosts, {:permanent_failure, 'smtp.gmail.com', :auth_failed}}}

but the error only happen on production, tried locally working good.

Then I changed the google account to the business account then working nicely.

So I think the problem is coming from SMTP account and (maybe) related to server IP address.

@princemaple it's already open in #785, I'll try the mentioned solution first I guess!
