rails 3: how can my app send from multiple email accounts? - ruby-on-rails

In my environment.rb file I have:
ActionMailer::Base.smtp_settings = {
:address => "smtp.example_host.com",
:port => '25',
:domain => "example_send_from.com",
:authentication => :plain,
:user_name => "send_account_name",
:password => ENV['MY_EMAIL_SEND_PWD']
}
It works fine.
However, now my app has a new class of emails that need to be sent via a different email account... perhaps gmail in some low-volume cases, sendgrid in other high volume cases.
I'm sure it's pretty simple -- but how do I override the default Base.smtp_settings setting on an email-by-email basis?

do you have separate actionmailers for each email account? then you could set the smtp settings per action mailer-class:
class Mailer1 < ....
self.smtp_settings = { .... }
end
etc.

Sendgrid set up on Rails 4

I have a rails 4 app. I set up ActionMailer and I can send order confirmation emails via localhost and gmail.
I installed Sendgrid on Heroku and followed the set up instructions. I get a Net::SMTPSyntaxError (501 Syntax error
my environment.rb (i have sendgrid user/pwd in application.yml)
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
in production.rb - the only actionamailer setting i have is this. I have this as a placeholder to put the real domain in later. I'm currently using herokuapp.com.
config.action_mailer.default_url_options = { host: 'localhost:3000' }
in my orders_controller within the order create method, I call the below.
AutoNotifier.orderconf_email(current_user, #order).deliver
auto_notifier.rb
class AutoNotifier < ActionMailer::Base
default from: "Test Email"
def orderconf_email(current_user, order)
#buyer = current_user
#order = order
mail(to: #buyer.email, subject: 'Thank you for your order.')
end
end
What am I missing? It works on localhost with gmail so I'm missing something in the sendgrid settings or in the default_url in production.rb file.
For posterity, here's a working setup for external SMTP in Rails on Heroku:
#config/environments/production.rb
config.action_mailer.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => 587, # ports 587 and 2525 are also supported with STARTTLS
:enable_starttls_auto => true, # detects and uses STARTTLS
:user_name => ENV["SENDGRID_USERNAME"],
:password => ENV["SENDGRID_PASSWORD"], # SMTP password is any valid API key, when user_name is "apikey".
:authentication => 'login',
:domain => 'yourdomain.com', # your domain to identify your server when connecting
}
Change default from: "Test Email" to valid email address, even example#example.com.
I would just like to point out, this is for sending emails via SMTP. While this method is totally ok, you should also consider sending via the API.
To do this, you need to specify an interceptor. Luckily, there's a Gem that helps with that. Here's a good article showing how to use it.
https://rubyplus.com/articles/561-Sending-Emails-using-SendGrid-API-in-Rails-4-1
It took us a long time to resolve the issue when we tried to deploy the SMTP relay on heroku. It worked perfectly fine on local but when pushed we received socket errors and time out issues. Eventually got it working.
Important note: Make sure not to use starttls_auto and SSL/or TLS this causes open SSL issue.

Do I need to provide a "from" email address while using Heroku + SendGrid?

I have the standard setup in config/environments/production.rb
config.action_mailer.default_url_options = { host: "myapp.heroku.com" }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:addresses => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
However, I encountered the following error while trying to send a mail:
ArgumentError: An SMTP From address is required to send a message. Set the message smtp_envelope_from, return_path, sender, or from address.
I then tried using the email I found on my heroku add-on page, i.e. app#######heroku.com, but now I got
Errno::ECONNREFUSED: Connection refused - connect(2)
So do I need to specify a from email or not? If yes, which one should I use?
Try this code in your production.rb file:
config.action_mailer.default_options = { from: "my_address#example.com" }
Yes you need to set a from address. All emails need an from address specified.
:from => "address_you_are_sending_from#your_domain.com"
This needs to be set in your _mailer.rb file. You can also set it gloablly in an initiallizer but it must always be referenced in your_mailer.rb files, and within each mail method itself.
You should change the :domain to a domain that you control. But if you were to use Heroku would your apps address not be yourapp.herokuapp.com instead of yourapp.heroku.com?
You can set a from address in your mailer file.
For example if you have an admin_mailer.rb for notifying your personal email of new activity on your site, it could look like this:
def new_customer_trial(customer_object)
#new_customer = customer_object
mail :to => "me#personal_email.com", :subject => "New Customer Trial", :from => "'My Site Notifications' <notifications#my_site.com>"
end
And you'd send that mail from a controller:
AdminMailer.new_customer_trial(customer_object)
or as a delayed job:
AdminMailer.delay.new_customer_trial(customer_object)

Specifying "from" email address when sending mail from Rails app

I'm using gmail to manage the email for my rails app domain.
The google account is, say, account_owner#gmail.com
But the "from" email address should be, say, info#mysite.com
When I configure smtp_settings as below, the email is sent, but the "from" email address is account_owner#gmail.com. I want it to be info#mysite.com, but if I change the :user_name to info#mysite.com and its password, my app seems to send the email, but it is never received. How can I achieve this?
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => "gmail.com",
:user_name => "account_owner#gmail.com",
:password => "thepassword",
:authentication => "plain",
:enable_starttls_auto => true
}
You cannot change the "from" address when sending mail via Gmail. (Unless maybe if you've configured that account to have other "send as" addresses, though I've never tested it)
I would suggest trying the free hosted Gmail for your domain, or use a third-party service like Mandrill.com
You shouldn't specify it as :user_name in your smtp_settings. Instead you should set the :from option like this:
ActionMailer::Base.default :from => 'info#mysite.com'
Alternatively you can set the from address when you send the email:
mail(:to => 'info#theirsite.com', :from => 'info#mysite.com' :subject => '...')

Rails - using multiple email providers in single app

Anyway I can use multiple email providers within the same Rails 3 app ?
Context
1. Im using postmark for sending out mails currently (using delayed job)
2. Our app also needs to send out some mass emails - for which we will be using a separate provider.
Now I dont want to separate out and create a new app for the mass emailing part. How can I use/choose different email providers at the point of sending email ?
Thanks in advance
You can override ActionMailer settings on a per mailer basis, for example
class BulkMailer < ActionMailer::Base
self.smtp_settings = {...}
end
will cause BulkMailer and its subclasses to use those settings.
The one thing to be wary of is not to change smtp_settings in place, i.e. do not do something like self.smtp_settings[:user_name] = 'blah' as this would be acting on the shared settings rather than creating new settings private to BulkMailer
I'm using mailserver fallback in my application, so when one mail server is down it switches mailserver. Your problem is similar, except you don't need to alias the old Mail::Message.deliver and use Mail::Message.mass_deliver for instance.
This is how you do it:
Mail::Message.class_eval do
def mass_deliver
self.delivery_method.settings = {
:address => "smtp.massdeliverserver.com",
:port => 587,
:domain => 'yourdomain.com',
:user_name => 'mass-email#quadnode.com',
:password => 'yourpassword',
:authentication => 'plain',
:enable_starttls_auto => true
}
deliver
end
end
Then you could use YourMailer.your_method.deliver to use defalt settings you provided in environment.rb for config.action_mailer.smtp_settings and YourMailer.your_method.mass_deliver to use the other server settings.
Put the code inside some file in config/initializers and mass_deliver method will be available for any Mail::Message instance in your application.
You have a mass email list to which you need to send out from say mass-email#email.com and some other emails for other purpose from otheremail#email.com
You need to do these steps if i am getting the question correct ::
Remove the default from default :from if you have written it.
Create an action mailer for mass-email and put up the :from => "mass-email#email.com"
Go to your environment.rb file and fill up the details like this
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'yourdomain.com',
:user_name => 'mass-email#quadnode.com',
:password => 'yourpassword',
:authentication => 'plain',
:enable_starttls_auto => true
}
You can create it for as many files as you wish.
Hope it helps.

Net::SMTPAuthenticationError 502 5.5.2 in Rails ActionMailer

i'm trying to send confirmation email to the user.
But i get following error:
Net::SMTPAuthenticationError (502 5.5.2 Error: command not recognized
Configuration in production.rb is following:
# Disable delivery errors, bad email addresses will be ignored
config.action_mailer.raise_delivery_errors = true
# set delivery method to :smtp, :sendmail or :test
config.action_mailer.delivery_method = :smtp
# these options are only needed if you choose smtp delivery
config.action_mailer.smtp_settings = {
:address => 'path_to_address_specified_by_my_hoster',
:port => 25,
:domain => 'my_domain.com',
:authentication => :plain,
:user_name => 'signup#my_domain.com',
:password => 'password'
}
I have created a mailbox in user profile at my hosting provider, named "signup#my_domain.com"
For created mailbox, they issued to me login and password:
login = verbose_login
password = verbose_password
I did't completely understood the exact format of :user_name.
Should i use
:user_name => "signup#my_domain.com"
or:
:user_name => "signup"
or:
:user_name => "verbose_login"
Or this field is specific to the mail server, and i must ask support of hosting provider ?
And what the difference between :authentication => :plain and :login ?
Thanks.
This works well for me:
config.action_mailer.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:domain => 'gmail.com',
:user_name => 'my_nick#gmail.com',
:password => 'secret_password',
:authentication => 'login',
:enable_starttls_auto => true
}

I have got the same error recently, and the reason was incorrect format of recipients
recipient = IO.readlines(emails_filename).first
mail(:to => recipient, :subject => subject)
Don't forget to add strip to get clean email addresses.
I had the same problem, but it is just a google configuration issue.
For some reason Google was blocking access from unknown location (app in production), so to solve this you can go to http://www.google.com/accounts/DisplayUnlockCaptcha and click continue (this will grant access for 10 minutes for registering new apps).
On the other hand, you could login to your gmail account, then go to https://www.google.com/settings/security/lesssecureapps and enable the access to less secure applications, which was the solution for me!
Please try to login with browser once.
There might be some issue with login (it will ask captcha etc).
Once you successfully logged-in, then try with Rails Mailer.
It should work now.
This issue generally happens with test account as we do not login via browser usually.
Then mail providers ask for confirmation like captcha, dob or answer of security question etc.
You've to use ActionMaliler::Base instead of config
ActionMailer::Base.smtp_settings #try this
config.action_mailer.smtp_settings #instead of this
Change your smtp code to below. It should work now.
ActionMailer::Base.smtp_settings = {
:address => 'path_to_address_specified_by_my_hoster',
:port => 25,
:domain => 'my_domain.com',
:authentication => :plain,
:user_name => 'signup#my_domain.com',
:password => 'password'
}
