Timeout Error Net::POP3

Hey, Im trying to run a daemon (using daemons gem) to check for email and then write to the console for every email in my inbox. The problem, is that I keep receiving timeout::error.

Heres my code

email.rb
require "net/pop"

loop do
  Net::POP3.start('mail.mylittlesecret.co.uk', 110,
                      'test+mylittlesecret.co.uk', 'somepassword') do |pop|
        if pop.mails.empty?
            puts 'No mail.'
        else
            pop.each_mail do |m|
              puts "mail"
            end
        end
      end
  
  sleep(10)
end
email_control.rb
require 'rubygems'
require 'daemons'

Daemons.run('email.rb')
(Im trying to run this in development, on rails 2.0 and ruby 1.8.6)

Thanks, Red

Hello,

Net::POP3 is up to date on the server with version(2.29). Also can you post the exact error logs that you are obtaining at your end.

Since you are mentioning a "time-out" issue, Can you check if the port 110 is blocked at your local end or not. You can either netstat (linux) or telnet (windows or linux) commands to check it out.

Hello,

Can you have a look into the following link.

http://www.ruby-doc.org/stdlib/libdoc/net/pop/rdoc/classes/Net/POP3.html

Maybe a few tweaking of the codes will help. Also there is no problems with the pop service on  the server. So the codes responsible for establishing connection with the server is failing.
Do let us know if this doesn't help you out.

Hey

I've played around with the code a bit more and still nothing. I had this problem at the start of the project so decided to come back to it.

Heres my new code
require "net/pop"

loop do
  
      pop = Net::POP3.new('mail.mylittlesecret.co.uk')
      pop.start('test+mylittlesecret.co.uk', 'something')             
      if pop.mails.empty?
        puts 'No mail.'
      else
          pop.each_mail do |m|   
            puts "mail Here"
          end
      end
      pop.finish
      
  sleep(10)
  
end

It takes roughly 70seconds for the telnet to connect, could this time length cause a timeout? If so is there a way I can change the timeout length?

Thanks for your help

You could try changing the timeout at

/usr/local/lib/ruby/1.8/timeout.rb:56:in `timeout'

but that shouldn't be it.  There must be something preventing the protocol connection (per the discussion above)

Also, check the "email.rb:19: syntax error, unexpected kEND, expecting $end (SyntaxError)"

Hey

Thanks for everyones help.

I fixed the problem by replacing mail.mylittlesecret.co.uk, with the ip

Thanks, Red
