Add Priority: Urgent and Importance: High headers like this:

Net::SMTP.start(‘[smtp.example.com](http://smtp.example.com)’, 25) do |smtp|  
smtp.open\_message\_stream(‘removed\_email\_address@domain.invalid’, [‘removed\_email\_address@domain.invalid’]) do  
|f|  
f.puts ‘Priority: Urgent’  
f.puts ‘Importance: High’  
f.puts ‘From: removed\_email\_address@domain.invalid’  
f.puts ‘To: removed\_email\_address@domain.invalid’  
f.puts ‘Subject: test message’  
f.puts  
f.puts ‘This is a test message.’  
end  
end

Hope this helps

Which are, of course, ignored by virtually every MTA on the planet,  
since RFC 2822 does not define these headers, nor the way they should be  
handled.

However they might be highlighted with a flag in the receiver’s MUA  
though, depending on what MUA they use, and perhaps that’s all you want.

There’s a list of non-standard or experimental headers you can try in  
RFC 2076 (see esp. section 3.9)
