Ruby Mail，如何实现 SSL 邮件

Question

我已通过此脚本成功地使用端口 25（非安全）将电子邮件发送到远程服务器：

require 'rubygems'
require 'mail'

options = { :address              => "mail.domain.com",
            :port                 => 25,
            :domain               => 'mail.domain.com',
            :user_name            => 'somedude@domain.com',
            :password             => 'topsecret',
            :authentication       => 'login',
            :enable_starttls_auto => true  }
 Mail.defaults do
  delivery_method :smtp, options
end

 mail = Mail.new do
      from 'someotherdude@otherdomain.com'
        to 'somedude@domain.com'
   subject 'This is a test email'
      body File.read('body.txt')
 end

puts mail.to_s
mail.deliver!

我现在需要做的是使用他们的 SSL 端口 466。当我尝试它时，我会得到详细说明消息的正常输出，然后它会暂停大约 2 分钟并咳出这个：

/usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/timeout.rb:60:in `rbuf_fill': execution expired (Timeout::Error)
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/protocol.rb:134:in `rbuf_fill'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/protocol.rb:116:in `readuntil'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/protocol.rb:126:in `readline'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/smtp.rb:911:in `recv_response'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/smtp.rb:554:in `do_start'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/smtp.rb:921:in `critical'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/smtp.rb:554:in `do_start'
        from /usr/local/rvm/rubies/ruby-1.8.7-p249/lib/ruby/1.8/net/smtp.rb:525:in `start'
        from /usr/local/rvm/gems/ruby-1.8.7-p249/gems/mail-2.2.10/lib/mail/network/delivery_methods/smtp.rb:127:in `deliver!'
        from /usr/local/rvm/gems/ruby-1.8.7-p249/gems/mail-2.2.10/lib/mail/message.rb:243:in `deliver!'
        from testmail.rb:30

我认为这是因为它甚至无法启动 SSL 身份验证过程。我该怎么做？

嗯，阅读 network/delivery_methods/smtp.rb，它看起来不支持 Direct SSL。 TLS 不一样，因为连接从纯文本开始，然后在 starttls 命令上切换到 SSL。你可以在端口 587 上使用 starttls 吗？

拉起我的评论。

见

How to send mail with ruby over smtp with ssl (not with rails, no TLS for gmail)

这表明您可以通过猴子修补 Net::SMTP 来做到这一点..

好吧，有点发现问题并可以解决它，但到目前为止，这个解决方案很糟糕......但它确实有效:)

#!/usr/bin/env ruby

require 'rubygems'
require "openssl"
require "net/smtp"
require "mail"

Net::SMTP.class_eval do

  def self.start( address, port = nil,
                  helo = 'localhost.localdomain',
                  user = nil, secret = nil, authtype = nil, use_tls = false,
                  use_ssl = true, &block) # :yield: smtp
    new(address, port).start(helo, user, secret, authtype, use_tls, use_ssl, &block)
  end

  def start( helo = 'localhost.localdomain',
             user = nil, secret = nil, authtype = nil, use_tls = false, use_ssl = true ) # :yield: smtp
    start_method = use_tls ? :do_tls_start : use_ssl ? :do_ssl_start : :do_start
    if block_given?
      begin
        send start_method, helo, user, secret, authtype
        return yield(self)
      ensure
        do_finish
      end
    else
      send start_method, helo, user, secret, authtype
      return self
    end
  end

  private

  def do_tls_start(helodomain, user, secret, authtype)
    raise IOError, 'SMTP session already started' if @started

    check_auth_args user, secret

    sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
    @socket = Net::InternetMessageIO.new(sock)
    @socket.read_timeout = 60 #@read_timeout
    @socket.debug_output = STDERR #@debug_output

    check_response(critical { recv_response() })
    do_helo(helodomain)

    raise 'openssl library not installed' unless defined?(OpenSSL)
    starttls
    ssl = OpenSSL::SSL::SSLSocket.new(sock)
    ssl.sync_close = true
    ssl.connect
    @socket = Net::InternetMessageIO.new(ssl)
    @socket.read_timeout = 60 #@read_timeout
    @socket.debug_output = STDERR #@debug_output
    do_helo(helodomain)

    authenticate user, secret, authtype if user
    @started = true
  ensure
    unless @started
      # authentication failed, cancel connection.
        @socket.close if not @started and @socket and not @socket.closed?
      @socket = nil
    end
  end

  def do_ssl_start(helodomain, user, secret, authtype)
    raise IOError, 'SMTP session already started' if @started

    check_auth_args user, secret

    sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
    raise 'openssl library not installed' unless defined?(OpenSSL)
    ssl = OpenSSL::SSL::SSLSocket.new(sock)
    ssl.sync_close = true
    ssl.connect
    @socket = Net::InternetMessageIO.new(ssl)
    @socket.read_timeout = 60 #@read_timeout
    @socket.debug_output = STDERR #@debug_output

    check_response(critical { recv_response() })
    do_helo(helodomain)

    do_helo(helodomain)

    authenticate user, secret, authtype if user
    @started = true
  ensure
    unless @started
      # authentication failed, cancel connection.
        @socket.close if not @started and @socket and not @socket.closed?
      @socket = nil
    end
  end

  def do_helo(helodomain)
     begin
      if @esmtp
        ehlo helodomain
      else
        helo helodomain
      end
    rescue Net::ProtocolError
      if @esmtp
        @esmtp = false
        @error_occured = false
        retry
      end
      raise
    end
  end

  def starttls
    getok('STARTTLS')
  end

  def quit
    begin
      getok('QUIT')
    rescue EOFError, OpenSSL::SSL::SSLError
    end
  end
end

options = {
  :address              => "mail.domain.net",
  :port                 => 466,
  :domain               => 'mail.domain.net',
  :user_name            => 'doon@domain.net',
  :password             => 'Secret!',
  :authentication       => 'login',
  :use_ssl => true  }

Mail.defaults do
  delivery_method :smtp, options
end

mail = Mail.new do
  from 'doon@domain.net'
  to 'doon@someotherdomain.com'
  subject 'This is a test email'
  body File.read('body.txt')
end

puts mail.to_s
mail.deliver!

由于某种原因，orig 猴子补丁中的 use_ssl 没有加入，并且与 Net::SMTP 中未定义的 VERSION 结合在一起。所以我改变了它，并强制 use_ssl 为真，并且能够发送电子邮件..

您的意思是使用端口 465 吗？这是标准的备用端口，而不是 466。您可能会超时连接到错误的端口。
