gem 'net-imap'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install net-imap

Usage

Connect with TLS to port 993

imap = Net::IMAP.new('mail.example.com', ssl: true)
imap.port          => 993
imap.tls_verified? => true
case imap.greeting.name
in /OK/i
  # The client is connected in the "Not Authenticated" state.
  imap.authenticate("PLAIN", "joe_user", "joes_password")
in /PREAUTH/i
  # The client is connected in the "Authenticated" state.
end

List sender and subject of all recent messages in the default mailbox

imap.examine('INBOX')
imap.search(["RECENT"]).each do |message_id|
  envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
  puts "#{envelope.from[0].name}: \t#{envelope.subject}"
end

Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"

imap.select('Mail/sent-mail')
if imap.list('Mail/', 'sent-apr03').empty?
  imap.create('Mail/sent-apr03')
end
imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
  if imap.capable?(:move) || imap.capable?(:IMAP4rev2)
    imap.move(message_id, "Mail/sent-apr03")
  else
    imap.copy(message_id, "Mail/sent-apr03")
    imap.store(message_id, "+FLAGS", [:Deleted])
  end
end
imap.expunge
