with rails 2.2.2 action mailer requires a valid ssl certificate i have a question about routing my smtp settings for my postfix are now ActionMailer::Base.smtp\_settings = { :address =\> “[smtp.mydomain.com](http://smtp.mydomain.com)”, :port =\> 25, :domain =\> “[mydomain.com](http://mydomain.com)”, :authentication =\> :plain, :user\_name =\> “removed\_email\_address@domain.invalid”, :password =\> “password” } both the email server and the rails app are on the same machine if i don’t have the address as 127.0.0.1 is it routing information through the internet instead of internally in the machine? if i use 127.0.0.1 i will get the ssl error because the host does not match up. ---

Hi, In your server’s host file map the address [smtp.mydomain.com](http://smtp.mydomain.com) to IP 127.0.0.1 so that it is not routed externally. -NAYAK ---

Hi, I am not sure of using multiple host/domain at a time there Try just 127.0.0.1 [smtp.mydomain.com](http://smtp.mydomain.com) NAYAK ---

I got it to work with the multiple domain names ActionMailer::Base.smtp\_settings = { :address =\> “[smtp.mydomain.com](http://smtp.mydomain.com)”, :port =\> 25, :domain =\> “[mydomain.com](http://mydomain.com)”, :authentication =\> :plain, :user\_name =\> “removed\_email\_address@domain.invalid”, :password =\> “password” } I have the address as [smtp.mydomain.com](http://smtp.mydomain.com) and it gives 127.0.0.1 in my mail error log. Instead of [ns1.mydomain.com](http://ns1.mydomain.com) . Is it working internally now?
