Topic: Actionmailer with GMail SMTP server
I've been trying to send emails with my gmail account for a while now, and thought I would share with you the working solution.
Turns out GMail supports only SSL SMTP mailing service, meaning if you cannot create a SSL connection to its SMTP server, you cannot send email through them. My Rails and Ruby (1.84) version do not yet support creating a SSL SMTP connection through Net::SMTP. DHH wrote about how to do so through installing msmtp, but I'd rather not use another application if I don't have to.
The dynamic nature of Ruby allows me to enhance the functionality of that class. I found the following answers from Stephen Chu's and a Japanese site, http://d.hatena.ne.jp/zorio/20060416 .
You must paste some files in your vendor/plugins directory...
vendor/plugins/action_mailer_tls/init.rb
require_dependency 'smtp_tls'vendor/plugins/action_mailer_tls/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)
raise 'openssl library not installed' unless defined?(OpenSSL)
starttls
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)
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')
end
def quit
begin
getok('QUIT')
rescue EOFError
end
end
endAnd your config/environments/development.rb or test.rb or production.rb, in your ActionMailer::Base's server settings if you have:
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.server_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => "mycompany.com",
:authentication => :plain,
:user_name => "username",
:password => "password"
}If you call your ActionMailer::Base's deliver method, it will send an email through GMail. That took me a little time to work through yesterday, so hopefully this can save someone some time.
