</div>

@pop = Net::POP3.new(‘[pop.163.com](http://pop.163.com)’)  
@pop.start(@username, @password)

```
@pop.each_mail do |m|
          # How can I get the subject of me$B!)e(B
    # e$B!A!A!A!A!A!A!A!A!A!A!A!A!A!A!A!Ae(B
    # By m.pop?
end

@pop.finish

```

By the way, can I only get the mail header? How?

Thank you!

Here is one way.

puts m.pop.scan(/Subject:(.+)$/)

You can use the header method if you are only interested in the header:

#!/usr/bin/env ruby

require ‘net/pop’  
pop = Net::POP.new(‘[pop.example.com](http://pop.example.com)’)  
pop.start(‘removed\_email\_address@domain.invalid’, ‘password’) do |pop|  
pop.each\_mail do |mail|  
puts mail.header.scan(/^Subject: (.+)/)  
end  
end
