    <p>I'm using my Gmail Apps for Domain account to send email within my rails application for standard automated emails (user signup, forgot password, notify admin of new comment, etc), but I'm worried about the 500 emails per day limit set by Google. </p> <p>Google suggests one way to overcome the limit is to use multiple user accounts. </p> <p>So, I've setup 10 additional gmail user accounts (noreply1, noreply2, noreply3, etc) - I'd like to track when any of these accounts has sent 500 emails in a 24 hour period and use the idle account accordingly. </p> <p>How do I dynamically set the <code>:user_name</code> value in <code>ActionMailer::Base.smtp_settings</code>?</p> <p>Here's my current setup - NOTE: this sends from "noreply1" every time, even though i'm explicitly setting :user_name and :from to "noreply2":</p> <pre><code>--- development.rb --- ActionMailer::Base.delivery_method = :smtp ActionMailer::Base.smtp_settings = { :address =&gt; "smtp.gmail.com", :port =&gt; "587", :domain =&gt; "mydomain.com", :authentication =&gt; :plain, :user_name =&gt; "noreply1@mydomain.com", :password =&gt; "password" } --- account.rb --- (MODEL, called via a callback) after_create :send_welcome_email ... def send_welcome_email #ActionMailer::Base.smtp_settings[:user_name] = 'noreply2@mydomain.com' ActionMailer::Base.smtp_settings.merge!({:user_name =&gt; "noreply2@mydomain.com"}) SubscriptionNotifier.deliver_welcome(self) end --- subscription_notifier.rb --- (MODEL) class SubscriptionNotifier &lt; ActionMailer::Base def welcome(account) @sent_on = Time.now @subject = "Welcome to the App" @recipients = account.email @from = "noreply2@mydomain.com" @body = { :account =&gt; account } end end </code></pre>

    1. COi think workmad3's idea of changing the ActionMailer::Base.smtp_settings hash is on the right track, I just can't figure out how to get rails to reload that hash's values with my dynamically set :user_name key.

    2. COWhat version of Rails are you using? Changing ActionMailer::Base.smtp_settings[:user_name] dynamically in a controller action works for me in 2.3.2. (At least, the hash changes. I didn't try sending mail.)

    3. COthat's the strange thing - the hash key value changes, but the email is sent using the original :user_name that was in my development.rb file

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
