Send email via Ruby code on Heroku - ruby

Question

I'm having problems sending email via my Ruby code. You can see my full code on GitHub.
UPDATE: the below code has been amended to reflect suggestions from #Gaurish
UPDATE2: looks like gmail refused the login attempt - I received an email from them to warn me some unknown application tried to access my account but they disabled it
The specific class is here:
require 'net/smtp'
=begin
http://apidock.com/ruby/v1_9_3_125/Net/SMTP/start/class
https://devcenter.heroku.com/articles/config-vars
I added the following config vars to Heroku
heroku config:add GM_USR=xxxx
heroku config:add GM_PSW=xxxx
=end
class Email
def initialize (to, from, subject, body)
#to = to
#from = from
#subject = subject
#body = body
#message = <<MESSAGE_CONTENT
From: User <#{#from}>
To: Integralist <#{#to}>
MIME-Version: 1.0
Content-type: text/html
Subject: #{#subject}
#{#body}
MESSAGE_CONTENT
#smtp = Net::SMTP.new('smtp.gmail.com', 587)
end
def send_email
#smtp.enable_starttls
#smtp.start('furious-wind-9309.herokuapp.com', ENV['GM_USR'], ENV['GM_PSW'], :login) do |smtp|
#smtp.send_message(#message, #from, #to)
end
end
end
I'm calling it like so:
email = Email.new('myemail#gmail.com', params[:email], 'test subject', params[:message]);
email.send_mail
But when I execute the code I get the error displayed on screen: 535-5.7.1 Please log in with your web browser and then try again. Learn more at
I checked the logs and I get...

I know people will likely suggest ActionMailer or Pony, but I'd rather not use those or have those suggested to me please. I'd instead like a solution that helps fix the above code instead.

Answer 1

[Update 1]
If gmail doesn't work for you, you can use SendGrid Addon which gives you upto 200emails per day at no charge.
Here is a sample(taken from docs) on how to use their STMP API with mail gem
require 'mail'
Mail.defaults do
delivery_method :smtp, { :address => "smtp.sendgrid.net",
:port => 587,
:domain => "yourdomain.com",
:user_name => "yourusername#domain.com",
:password => "yourPassword",
:authentication => 'plain',
:enable_starttls_auto => true }
end
mail = Mail.deliver do
to 'yourRecipient#domain.com'
from 'Your Name <name#domain.com>'
subject 'This is the subject of your email'
text_part do
body 'Hello world in text'
end
html_part do
content_type 'text/html; charset=UTF-8'
body '<b>Hello world in HTML</b>'
end
end
Using Sendgrid is much better solution because you also get access Advanced reporting & analyticss which are not available with gmail. Also, there is no restriction on "from" addresses in sendgrid.
With Heroko, you can't send emails directly from localhost because Heroku does not provide an outgoing mail service.
so you will have to consider an external smtp server for sending your emails. popular ones are Gmail & Sendgrid
this is just one trade-off of using a cloud computing platform like heroku.
With Gmail, try doing something like this:
require 'net/smtp'
msg = "your message goes here"
smtp = Net::SMTP.new 'smtp.gmail.com', 587
smtp.enable_starttls
smtp.start(YourDomain, YourAccountName, YourPassword, :login) do
smtp.send_message(msg, FromAddress, ToAddress)
end

Answer 2

If you try:
#email = Email.new('mark.mcdx#gmail.com', params[:email], 'test subject', params[:message])
#email.send_email

Answer 3

Just load up SendGrid as an add-on and it works right out of the box. Plus you get a whole suite of analytics for troubleshooting bounces, deliveries, etc...
