Here's my simple test program (using ActionMailer 3.0.8, Ruby 1.9.2p180 Mac OS X):
require 'rubygems'
require 'action_mailer'
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "my_exchange_server",
:port => 25,
:domain => 'my_domain.org',
:authentication => :login,
:user_name => 'my_user',
:password => 'my_password',
:enable_starttls_auto => false
}
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.default :from => 'from_email@my_company.com'
m = ActionMailer::Base.mail :to => 'to_email@my_company.com', :subject => 'this is a test', :body => 'this is a test'
m.deliver
Trying various authentication types I get the following errors:
:plain error:
smtp.rb:966:in `check_auth_response': 504 5.7.4 Unrecognized authentication type. (Net::SMTPAuthenticationError)
:login error:
smtp.rb:972:in `check_auth_continue': 504 5.7.4 Unrecognized authentication type. (Net::SMTPSyntaxError)
:cram_md5 error:
smtp.rb:972:in `check_auth_continue': 504 5.7.4 Unrecognized authentication type. (Net::SMTPSyntaxError)
No authentication error:
protocol.rb:135:in `read_nonblock': end of file reached (EOFError)
Any ideas?
It could be: none, plain, login, cram_md5, NTLM, StartTLS
250-AUTH LOGIN
" or "250-AUTH=LOGIN
" indicate that you need to authenticate.250-AUTH
" (with nothing else following on that line!) seems to indicate that you should NOT authenticate yourself! Otherwise you will get the error:
Good resources that should help you to understand and troubleshoot it.
(instead of changing how you access Exchange)
