Having trouble sending emails with Gmail after setting up action_mailer_optional_tls in Rails

Hey everyone, I’m really stuck here. I’ve been trying to set up email sending with Gmail in my Rails 2.3.2 project using Ruby 1.8.6. I installed the action_mailer_optional_tls gem, but it’s not working as expected.

When I try to send an email, I keep getting this error:

530 5.7.0 Must issue a STARTTLS command first

I’ve been banging my head against the wall trying to figure this out. Has anyone managed to get this working? Any tips or tricks you can share? I’d really appreciate some help here. Thanks in advance!

hey mate, i had similr issue few months back. hve u tried using smtp_tls gem instead? it worked like charm for me. also, double check ur gmail settings - make sure ‘less secure app access’ is turned on. hope this helps!

I’ve dealt with this exact problem before, and it can be quite frustrating. One thing that helped me was explicitly setting the TLS configuration in my mailer settings. Try adding this to your environment.rb or an initializer:

ActionMailer::Base.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => 'your_domain.com',
  :user_name            => '[email protected]',
  :password             => 'your_password',
  :authentication       => 'plain',
  :enable_starttls_auto => true
}

Make sure to replace the placeholder values with your actual information. This configuration forces the use of TLS, which should resolve the STARTTLS error you’re encountering. If you’re still having issues after this, it might be worth checking your Gmail account settings or considering using an app-specific password instead of your regular Gmail password.

I encountered a similar issue when working with Rails 2.3.2 and Ruby 1.8.6. Have you verified your Gmail account settings? Ensure that you’ve enabled ‘Allow less secure apps’ in your Google Account security settings. Also, double-check your SMTP configuration in your environment.rb file. Make sure the port is set to 587 and enable_starttls_auto is true. If you’re still facing issues, consider using an application-specific password instead of your regular Gmail password. This approach often resolves STARTTLS-related problems. Lastly, if all else fails, you might want to explore alternative gems like ‘smtp_tls’ as a workaround for older Rails versions.
