Hi, Guys,  
I can read my [sina.com](http://sina.com) email by the following code:  
require ‘net/pop’  
Net::POP3.foreach(‘_[pop3.sina.com.cn](http://pop3.sina.com.cn)_’, 110,  
‘removed\_email\_address@domain.invalid’, ‘my\_password’ ) do |email|  
hdr = email.header  
if hdr =~ /\d+/  
language = hdr.to\_s  
else  
language = “INVALID”  
end  
puts language  
end

I would like to send email by _[smtp.sina.com.cn](http://smtp.sina.com.cn)_, there is code on the  
net:

Net::SMTP.start(‘[smtp.sina.com.cn](http://smtp.sina.com.cn)’,25) do |smtp|  
smtp.send\_message “hello”, ‘removed\_email\_address@domain.invalid’, [‘removed\_email\_address@domain.invalid’]  
end  
But I get error message:  
_e:/ruby/lib/ruby/1.8/net/smtp.rb:680:in `check\_response’: 530  
Authentication required (Net::SMTPUnknownError)_

So, how can make it I can send the email by the ruby code?

Any suggestion would be quite appreciated.

Thanks.  
Wesley C…

I haven’t needed to, but a Google search should find you quite a few  
hits.
