RIF. Ugh, what a shame.

Have you configured OpenDKIM correctly? This tutorial might give you an idea or two. Gmail won’t relay mail unless its signed by your domain.

Yes. You can use an existing SMTP server (gmail [legacy app mode], yahoo, microsoft, etc). One thing to keep in mind – if you decide to go that route don’t use your personal account because the address might be exposed in the mail headers. Create a dedicated account and use that instead.

email: {
    smtp_server: "smtp.example.tld:[port]" # port 25, port 587, etc
    smtp_login: "username"
    smtp_password: "password"
    smtp_from_address: "noreply@example.tld" # or account_just_created@example.tld
    tls_type: "tls" # or starttls
}
