I haven’t found any example. Neither have I been able to even authenticate using the library Swooth .

Is there any example? Has anyone done that?

my own Postfix server, SSL/TLS

# config/config.exs
config :sample, Sample.Mailer,
  adapter: Swoosh.Adapters.SMTP,
  relay: "smtp.avengers.com",
  username: "tonystark",
  password: "ilovepepperpotts",
  ssl: true,
  tls: :always,
  auth: :always,
  port: 1025,
  dkim: [
    s: "default", d: "domain.com",
    private_key: {:pem_plain, File.read!("priv/keys/domain.private")}
  ],
  retries: 2,
  no_mx_lookups: false

Have you tried not using the ssl: true flag? It might override the port setting and force it to 465.

3

No, because on my postfix ssl is mandatory

Like I said, it might fix the port to 465, so give it a try.

Just consider also other mail servers that also support REST API like Postal.
We use this as an alternative to Sendgrid. (side by side)

It’s closed on the server

I think we’re talking past each other. If you set ssl: true, gen_smtp sets the port to 465. If you want to use TLS on port 1025, you have to remove ssl: true.

I just tried with my own postfix server. With ssl: true, :gen_smtp returns

{:error, :retries_exceeded,
 {:network_failure, 'my.mail.server',
  {:error, {:tls_alert, 'bad record mac'}}}}

With ssl: false, the mailing is sucessful:

"2.0.0 Ok: queued as E11D9140608\r\n"

If on your return you cannot be respectful we will unfortunately have no choice but to close your account.
