我开始使用 Ruby 解析电子邮件。我正在尝试从我的 GMail 帐户中读取：

require 'rubygems'
require 'mail'

Mail.defaults do
  retriever_method :imap, :address    => "imap.gmail.com",
                          :port       => 995,
                          :user_name  => 'example@gmail.com',
                          :password   => 'password',
                          :enable_ssl => true
end

emails = Mail.all

emails.each do |email|
    puts email.inspect
end

...但我收到此错误：

Ruby 的 IMAP 解析器有错误。您的错误输出表明问题不太可能出在您的代码中，很可能是 Ruby IMAP 解析器代码，如果不修补 Ruby，您将无法轻易更改。

如果您只是对 Gmail 感兴趣，并且想尝试更简单的解决方案，请尝试使用 Gmail gem：

如果您尝试在 POP3 邮件服务器上执行 IMAP，则此错误消息很典型。

Google Mail 的 IMAP 端口是 993。您尝试的端口是 POP3。
