GMail SMTP with Ruby on Rails and ActionMailer

Trying to use GMail SMTP (or some other SMTP authenticated with TLS) with ActiveRecord to send email in Ruby on Rails? Up till now this involved requiring smtp_tls.rb in your environment.

Thankfully, Kyle Maxwell has come up with a neater solution.

Install

It’s a plugin, which you can get with this command in your Rails root…

~~./script/plugin install http://svn.kylemaxwell.com/rails_plugins/action_mailer_optional_tls/trunk/~~

Due to continued downtime of Kyle’s site please use the following URl:

./script/plugin install http://svn.douglasfshearer.com/rails/plugins/action_mailer_optional_tls

Setup

You can turn TLS authentication on and off as you need in your environment with a new key that is added to the smtp config, tls. To use with gmail, the following should be in your environment.rb...


ActionMailer::Base.smtp_settings = {
    :tls => true,
    :address => "smtp.gmail.com",
    :port => "587",
    :domain => "YOURDOMAIN",
    :authentication => :plain,
    :user_name => "GOOGLEUSERNAME",
    :password => "GOOGLEPASSWORD" 
  }

And that’s it. Enjoy.

Looks like Kyle's site is down, I shall email you the plugin.

This plugin is a new one that does the same thing as the one you link to, but is almost 2 years newer and Rails 2.0 compatible.

Any chance I could get in on that e-mail? I'd really appreciate it.

This plugin is now hosted on my SVN until Kyle's site reappears.

Thanks.

Thanks.

It works when sending e-mails to gmail accounts.

But e-mails sent to hotmail accounts will not even reach the spam box.

Is it a wrong setting?
Is it that hotmail discards every mail send via gmail smtp relay?

If that is the case, this mailer setup cannot be used in production mode.

I've been trying to get something like this working since I use Google Apps for about 5 hours and nothing quite worked until now. Thank you big time!

There is a change in ruby 1.8.7 that breaks this app.

The symptom is an error like "(wrong number of arguments (3 for 2))" when sending a mail via tls.

The quick fix until the authors make a permenant fix is to remove authtype from the call to check_auth_args on line 33 of action_mailer_optional_tls/lib/smtp_tls.rb
