#61 Sending Email (revised)

I would like to note that if you want use image_tag in a mailer you have to set

config.action_mailer.asset_host = 'www.yourhost.com'

so that image_tags have the right source in the email

it will turn this

 # all images are broken
<img src="/images/icon.png" alt="Icon" />

into this

 # all images are fine
<img src="www.yourhost.com/images/icon.png" alt="Icon" />

since config.action_mailer.default_url_options has no effect on image_tag

Can someone point me in the right direction on how to set up environment variables in rails?

Where for example would ENV["GMAIL_USERNAME"] = 'secret' be saved?

Thanks, Ryan. Being able to see the email in the browser sure beats looking at the markup in the logs and imagining how it might look!

Any thoughts on sending multiple e-mails such as a newsletter? A block perhaps?

How did you get the image on the railscasts.example@gmail.com? Address book or some gravatar-like service? :)

I am having issues setting up my mail server (Mac Mini using Lion Server). I get different answers on how to set this up when I call technical support. When I try to send emails it sits until it times out. It is looking for something on my server but I do not know what information to put where. This brings me to my question.

For ease I wanted to use my Gmail smtp settings for my Rails applications. However it appears that Gmail will force the FROM value to the Gmail email address and name (if one is set up) regardless of what the FROM value in the mailer is. Is there any way around this using Gmail? If not are there other email services that are as easy to configure as Gmail is but do not force the FROM value to be the email address? This was not addressed in this railscast.

I'd love to send the email not only to the user but to myself as well. How would you do that?

I have added an interceptor (it sends email to the the admin) but then it stops sending the email to the user for some reason. I don't know why... I posted the question on Stackoverflow: http://stackoverflow.com/questions/11539690/rails-3-mailer-interceptor-conflicting

What is the reason that it sends empty e-mails ??

Hi Ryan,

I signed up on Railcasts today and now i feel like a kid in candy store. Too much of exciting stuff.

However, my excitement is bit tampered...I guess am having difficulty finding the right episodes.

After going through this episode, I am able to get email working but stuck at one place.

my config:

ActionMailer::Base.default_url_options = {host: "localhost:3000"}

works perfectly. But how do I make the host dynamic? I will be using heroku to host multiple domains for the same app. So my hosts will be sub1.mydomain.com, sub2.mydomain.com etc.

If you have already covered this in another episode, can you point me to it please.

Regards,
Murty

Just a small note in case others had the same issue i did:

This:
# specify what domain to use for mailer URLs
config.action_mailer.default_url_options - { host: "localhost:3000" }

Should actually be:
# specify what domain to use for mailer URLs
config.action_mailer.default_url_options = { host: "localhost:3000" }

Once i changed the - to an =, it worked fine. Thanks again for a great railscast and gem!

I've followed this tutorial just like it is but it gave me this:

SMTP error: 530 5.5.1 Authentication Required.

i've google it everywhere and finally i could! using the SMTP configuration like this:

puts "config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => 'catec.edu.bo',
  :user_name            => '<USER>@gmail.com',
  :password             => '<PASSWORD>',
  :authentication       => 'plain',
  :enable_starttls_auto => true  }"

I hope it helps,
Best Regards!

When you use a command like:

UserMailer.signup_confirmation(@user).deliver

does .deliver return a result? That is, is:

result = UserMailer.signup_confirmation(@user).deliver

valid code, and what, if anything, gets returned. I'm trying to figure out a way to catch an error if the smtp server is down.

Hi I just want to ask on how to configure live email account by Microsoft on

config/environments/development.rb
config.action_mailer.default_url_options = { host: "example.com" }
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address: "smtp.gmail.com",
  port: 587,
  domain: "localhost",
  authentication: "plain",
  enable_starttls_auto: true,
  user_name: ENV["GMAIL_USERNAME"],
  password: ENV["GMAIL_PASSWORD"]
}

how about the live email account configuration that is similar with gmail smtp configuration?
example
username: myemail@live.com
password: SamplePassword

Thanks!

There is a typo in the ASCIIcast; In the code block for adding the default url options it's specified as "- { host" but should be "= { host".

Great railscast! I didn't like the gmail option but found this awesome blog post which explains how to start postfix on your mac and send mail from that - no passwords or environment variables required

http://andr.esmejia.com/posts/20-send-real-mail-with-rails-from-your-development-environment-on-mac-os-x

In brief:

in terminal do
sudo postfix start

In config/environments/development.rb :
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "localhost",
:port => 25,
:domain => "whatever.com",
}

Worked great on Mac OSX Lion, Rails 3.2

Remember to look in your gmail spam folder for the email (on gmail.com not just Mac Mail app)
