Need help on reading emails with "mail" gem in ruby

I am doing automation using Watir that creates an email that I need to check. I was pointed at the email gem as being the easiest way to do this.

I added following code and am able to get first email from my inbox.

require 'mail' 
 require 'openssl'
 
 Mail.defaults do 
   retriever_method :pop3, :address    => "email.someemail.com", 
                           :port       => 995, 
                           :user_name  => 'domain/username', 
                           :password   => 'pwd', 
                           :enable_ssl => true 
 end 
 
 puts Mail.first 
 

I am new to this forum and have following questions :

1. How can I get all the unread emails? I tried Mail.all, Mail.first, Mail.last, but nothing returns unread email.




2. How can I get all links that are present inside emails? Or mail message body from the specific email? I need to get the email body of first unread email.




3. How can I get emails from a specific folder, if I have subfolders inside my inbox?
