如何使用ruby on rails检查电子邮件地址？

有没有任何宝石插件？

我能找到的任何电子邮件地址都是实时的。

查看ActiveModel::Validator中集成的Email validator based on DNS，这意味着您可以在Rails app中使用它：

require 'resolv'

class EmailValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    if Resolv::DNS.new.getresources(value.split("@").last, Resolv::DNS::Resource::IN::MX).empty?
      record.errors[attribute] << (options[:message] ||  "does not have a valid domain")
    end
  rescue Resolv::ResolvError, Resolv::ResolvTimeout
    record.errors[attribute] << (options[:message] ||  "does not have a valid domain")
  end
end

And this code i use in my sent email script：

require 'resolv'

module MailMachine
  class Validator
    def initialize(name)
      @name = name.split('@').last
    end

    def servers_list
      Resolv::DNS.open.getresources(@name, Resolv::DNS::Resource::IN::MX).map do |resolv|
        resolv.exchange.to_s
      end    
    end

    def server
      servers_list.find do |name|
        Resolv.getaddress(name) =~ Resolv::AddressRegex
      end
    rescue Resolv::ResolvError => e
      #holly molyy
      return false if e.is_a? Exception
    end
  end
end
