Configuring Rails To Use Gmail’s SMTP Server

Nothing original here I am afraid.
I copied Google's cache from http://blog.pomozov.info/posts/how-to-send-actionmailer-mails-to-gmailcom.html


  1. Save the following code within your rails app in lib/smtp_tls.rb




require "openssl"
require "net/smtp"

Net::SMTP.class_eval do
private
def do_start(helodomain, user, secret, authtype)
raise IOError, 'SMTP session already started' if @started
check_auth_args user, secret, authtype if user or secret

sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
@socket = Net::InternetMessageIO.new(sock)
@socket.read_timeout = 60 #@read_timeout
#@socket.debug_output = STDERR #@debug_output

check_response(critical { recv_response() })
do_helo(helodomain)

if starttls
raise 'openssl library not installed' unless defined?(OpenSSL)
ssl = OpenSSL::SSL::SSLSocket.new(sock)
ssl.sync_close = true
ssl.connect
@socket = Net::InternetMessageIO.new(ssl)
@socket.read_timeout = 60 #@read_timeout
#@socket.debug_output = STDERR #@debug_output
do_helo(helodomain)
end

authenticate user, secret, authtype if user
@started = true
ensure
unless @started
# authentication failed, cancel connection.
@socket.close if not @started and @socket and not @socket.closed?
@socket = nil
end
end

def do_helo(helodomain)
begin
if @esmtp
ehlo helodomain
else
helo helodomain
end
rescue Net::ProtocolError
if @esmtp
@esmtp = false
@error_occured = false
retry
end
raise
end
end

def starttls
getok('STARTTLS') rescue return false
return true
end

def quit
begin
getok('QUIT')
rescue EOFError, OpenSSL::SSL::SSLError
end
end
end



  1. Add this code to config/environment.rb

    require “smtp_tls”

    ActionMailer::Base.smtp_settings = {
    :address => “smtp.gmail.com”,
    :port => 587,
    :authentication => :plain,
    :user_name => “someone@openrain.com”,
    :password => ’someonesPassword’
    }

  2. Use ActionMailer as normal.

Thanks for retrieving this lost file! Maybe you could also state that the code is saved in lib/smtp_tls.rb just to save people going to the other blog as well :)
