Net::POP3

This library provides functionality for retrieving
email via POP3, the Post Office Protocol version 3. For details
of POP3, see RFC1939.

Installation

Add this line to your application’s Gemfile:

gem 'net-pop'

And then execute:

$ bundle

Or install it yourself as:

$ gem install net-pop

Usage

This example retrieves messages from the server and deletes them
on the server.

Messages are written to files named ‘inbox/1’, ‘inbox/2’, ….
Replace ‘pop.example.com’ with your POP3 server address, and
‘YourAccount’ and ‘YourPassword’ with the appropriate account
details.

require 'net/pop'

pop = Net::POP3.new('pop.example.com')
pop.start('YourAccount', 'YourPassword')             # (1)
if pop.mails.empty?
  puts 'No mail.'
else
  i = 0
  pop.each_mail do |m|   # or "pop.mails.each ..."   # (2)
    File.open("inbox/#{i}", 'w') do |f|
      f.write m.pop
    end
    m.delete
    i += 1
  end
  puts "#{pop.mails.size} mails popped."
end
pop.finish                                           # (3)
  1. Call Net::POP3#start and start POP session.
  2. Access messages by using POP3#each_mail and/or POP3#mails.
  3. Close POP session by calling POP3#finish or use the block form of #start.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
