Rails 3.2.1 actionmailer setup

I'm having difficulty setting up ActionMailer on signup:


ActionMailer::Base.smtp_settings = {
 :address              => "smtp.gmail.com",
 :port                 => "587",
 :domain               => "mail.gmail.com",
 :user_name            => "my_gmail_user_name",
 :password             => "my_gmail_pw",
 :authentication       => "plain",
 :enable_starttls_auto => true

ActionMailer::Base.default_url_options[:host] = "localhost:3000"
Mail.register_interceptor( DevelopmentMailInterceptor ) if Rails.env.development?


def create
  @user = User.new( params[:user] )

  respond_to do |format|
    if @user.save
      UserMailer.welcome_email( @user ).deliver

      format.html{ redirect_to( @user, :notice => 'Account successfully created.' ) }
      format.json{ render :xml => @user, :status => :created, :location => @user }
      format.html { render :action => "new" }
      format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }


class UserMailer < ActionMailer::Base
  default :from "no-reply@myapp.com"

  def welcome_email( user )
    @user = user
    @url = "http://localhost:3000/login"
    mail( :to => user.email, :subject => 'Welcome to app' )


class DevelopmentMailInterceptor
  def self.delivering_email(message)
    message.subject = "#{message.to} #{message.subject}"
    message.to = "mydump@email.com"

I'm not getting any emails sent to my dump email in DevelopmentMailInterceptor.


gmail is anal! Is there anyway you can use a different smtp host? I think, due to overly aggressive spam detection, they will silently reject smpt requests that they consider 'potential spam'. Potential Spam in your case means emails directed to be from an address OTHER than "mail.gmail.com", which in your case is "email.com".

I think using gmail as an SMTP host for a Rails app is a loosing proposition, I use godaddy.com (smtpout.secureserver.net) for my rails apps, and have no problems.
