I’ve been trying to get my action mailer powered form to work all day. I can get it to work perfectly in development mode. But when I run it in production mode I get an error, the log spits this out Net::SMTPSyntaxError (501 Syntax: HELO hostname ): /usr/lib/ruby/1.8/net/smtp.rb:680:in `check_response' /usr/lib/ruby/1.8/net/smtp.rb:653:in `getok’ /usr/lib/ruby/1.8/net/smtp.rb:623:in `helo' /usr/lib/ruby/1.8/net/smtp.rb:401:in `do\_start’ /usr/lib/ruby/1.8/net/smtp.rb:378:in `start' /usr/lib/ruby/1.8/net/smtp.rb:316:in `start’ /usr/lib/ruby/gems/1.8/gems/actionmailer-1.1.5/lib/action\_mailer/base.rb:436:in `perform_delivery_smtp' /usr/lib/ruby/gems/1.8/gems/actionmailer-1.1.5/lib/action_mailer/base.rb:327:in `send’ /usr/lib/ruby/gems/1.8/gems/actionmailer-1.1.5/lib/action\_mailer/base.rb:327:in `deliver!' /usr/lib/ruby/gems/1.8/gems/actionmailer-1.1.5/lib/action_mailer/base.rb:223:in `method\_missing’ /app/controllers/email\_controller.rb:9:in `message' /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:853:in `send’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/base.rb:853:in `perform_action_without_filters' /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/filters.rb:332:in `perform\_action\_without\_benchmark’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/benchmarking.rb:69:in `perform_action_without_rescue' /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/benchmarking.rb:69:in `measure’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/benchmarking.rb:69:in `perform_action_without_rescue' /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/rescue.rb:82:in `perform\_action’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/base.rb:369:in `send' /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:369:in `process\_without\_session\_management\_support’ /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/session\_management.rb:116:in `process' /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/dispatcher.rb:38:in `dispatch’ /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/fcgi\_handler.rb:141:in `process_request' /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/fcgi_handler.rb:53:in `process!’ /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/fcgi\_handler.rb:52:in `each_cgi' /usr/lib/ruby/1.8/fcgi.rb:597:in `each’ /usr/lib/ruby/1.8/fcgi.rb:597:in `each_cgi' /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/fcgi_handler.rb:52:in `process!’ /usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/fcgi\_handler.rb:22:in `process!’ dispatch.fcgi:24 I looked into HELO and it seems to have something to do with the hostname obviously but I cant see anything wrong with it. my production.rb code is ActionMailer::Base.server\_settings = { :address =\> “[mail.pulsedev.net](http://mail.pulsedev.net)”, :port =\> 25, :domain =\> “[pulsedev.net](http://pulsedev.net)”, :authentication =\> :login, :user\_name =\> “m9472838”, :password =\> “sirius”, } Any help would be great thanks ---

It works fine in development mode so I dont see how it could be that. But on the other hand I’ve tried everything in production.rb. ---

I had this same problem and was able to get it to work by changing this line in my production.rb file: #config.action\_mailer.raise\_delivery\_errors = false Uncomment that line (which is the default in the development.rb) and it should send emails - I consider this a workaround because I could not determine the actual source of the error.
