Description

一种邮件发送方法、邮件控制方法、发送端及接收端 技术领域
本发明涉及通信技术领域，尤其涉及一种邮件发送方法、邮件控制方法、发送端及接收端。
背景技术
随着科技的发展，电子邮件的应用范围越来越广,电子邮件是人们日常工作常用的办公通信工具，技术人员在工作过程中会频繁利用办公电脑、个人电脑、手机等电子产品收发电子邮件，因此，电子邮件的信息安全就变得尤其重要。由于很多电子邮件内容涉及重要机密、未公开信息或敏感数据等，而邮件发送人在将邮件发送出去之后，接收端可以对邮件进行随意传播或者公开，而重要邮件被公开后可能产生恶劣的影响，同时也对邮件发送人带来不必要的麻烦，由此可见，现有技术中的邮件传播存在着安全性较低的技术问题。
发明内容
鉴于上述问题，本发明提出了一种克服上述问题或者至少部分地解决上述问题的一种邮件发送方法、邮件控制方法、发送端及接收端。
第一方面，本发明实施例提供一种邮件发送方法，包括：
发送端获得原始邮件；
所述发送端为所述原始邮件添加第一扩展信息，从而获得处理后的所述原始邮件；
所述发送端将所述处理后的所述原始邮件发送至接收端，以供所述接收端基于所述第一扩展信息实现对所述原始邮件的操作权限的控制。
第二方面，本发明实施例提供一种邮件控制方法，包括：
接收端接收发送端发送的邮件；
所述接收端读取所述邮件中由所述发送端添加的第一扩展信息；
所述接收端根据所述第一扩展信息实现对所述邮件的操作权限的控制。
第三方面，本发明实施例提供一种发送端，包括：
获取单元：用于获得原始邮件；
添加单元：用于为所述原始邮件添加第一扩展信息，从而获得处理后的所述原始邮件；

第六方面，本发明实施例一种计算机可读介质，其中存储了如上所述的计算机程序。
本申请实施例中提供的技术方案，至少具有如下技术效果或优点：
根据本发明的邮件发送方法，在发送端发送原始邮件前，需要为所述原始邮件添加第一扩展信息，之后再发送至接收端，从而接收端在接收到发送端发送的邮件之后，可以基于邮件中所包含的第一扩展信息实现对原始邮件的操作权限的控制，以此来控制收件人对接收邮件的操作权限，以此来避免邮件接收方可以随意对邮件进行处理的情况，从而达到提高邮件收发安全性的技术效果；
同时，从本发明技术方案实现过程来看，对原始邮件的操作权限是由发送端在原始邮件中添加第一扩展信息来完成的，实现过程中无需邮件服务器的参与，只要接收客户端能识别并提取到第一扩展信息就能实现对接收邮件的操作权限的控制，因此说，本发明技术方案对邮件服务器没有任何限制，只对收发客户端有要求，特定邮件客户端搭配任意服务器均可完成对收件人操作权限的控制，这样使用范围更广，普及率会更高。
上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，而可依照说明书的内容予以实施，并且为了让本发明的上述和其它目的、特征和优点能够更明显易懂，以下特举本发明的具体实施方式。

本发明实施例提供一种邮件发送方法、邮件控制方法和装置，用以解决现有技术中邮件的安全性较低的技术问题。
请参考图1，本申请实施例提供的一种邮件发送方法，该方法包括：
S101：发送端获得原始邮件；
S102：所述发送端为所述原始邮件添加第一扩展信息，从而获得处理后的所述原始邮件；
S103：所述发送端将所述处理后的所述原始邮件发送至接收端，以供所述接收端基于所述第一扩展信息实现对所述原始邮件的操作权限的控制。
需要说明的是，在具体实施过程中，本申请提供的上述邮件发送方法可应用于使用任意协议收发邮件的邮件客户端，例如：IMAP(Internet Mail Access Protocol，交互式邮件存取协议)、POP3(Post Office Protocol 3，邮局协议的第3个版本)、SMTP(Simple Mail Transfer Protocol，简单邮件传输协议)、ESMTP(Extended SMTP，扩展SMTP)等协议。且该邮件客户端可以搭建各种邮件服务器来使用，只需按照相关邮件服务器地址完成配置即可，举例来说明，如某邮件客户端要使用SINA邮件服务器，可配置接收邮件服务器地址(POP3)为：pop.sina.com.cn或：pop3.sina.com.cn，发送邮件服务器地址(SMTP)为：smtp.sina.com.cn，即可使用，该方法应用广泛，操作方便。
下面，结合图1详细介绍本邮件发送方法的具体实现步骤：
步骤S101，发送端获得原始邮件。这里的原始邮件的邮件格式不做限制，为目前广泛应用的一种电子邮件技术规范MIMO，全称为“MultipurposeInternetMailExtensions”，比较确切的中文名称为“多用途互联网邮件扩展”，MIME邮件由邮件头和邮件体两大部分组成，邮件头包含了发件人、收件人、主题、时间、MIME版本、邮件内容的类型等重要信息，主要格式及内容例如如下(当然，以下格式仅仅作为举例，还可以为其他格式，本发明实施例不作限制)：
Date:Tue,31 Jan 2012 10:07:39+0800
From:abc<abc@domain.com>
To:zhang<abc@test.com>
Subject:＝？gb2312？B？1vfM4g＝＝？＝
X-Priority:3
Mime-Version:1.0
Message-ID:<201201311007392182841@domain.cn>
Content-Type:multipart/related；
boundary＝"----＝_001_NextPart076188650547_＝----"
其中原始邮件的邮件内容可包含文本、图像、声音、以及各种附件格式等。
步骤S102，发送端为原始邮件添加第一扩展信息，从而获得处理后的原始邮件。
其中，在本申请实施例中，第一扩展信息用于控制接收端对原始邮件进行转发和/或回信的操作权限，例如：通过第一扩展信息控制接收端对原始邮件禁止转发、禁止回信、禁止转发且禁止回信等等。需要说明的是，第一扩展信息还可用于限制接收端对接收邮件进行存档、打印等日常邮件客户端可见的操作权限，本发明中不做限制。
作为一种可选的实施例，如果所述第一扩展信息中包含第一预设内容，则所述接收端对所述原始邮件的操作权限为禁止转发；和/或，如果所述第一扩展信息中包含第二预设内容，则所述接收端对所述原始邮件的操作权限为禁止回信。
其中，第一扩展信息可以包含多种扩展信息，例如：第一功能字段、第一功能标记等等，基于第一扩展信息不同导致第一预设内容(或者第二预设内容)也不同，对于第一预设内容(或者第二预设内容)为何种内容将在后续进行介绍。接收端在接收到处理后的原始邮件之后，可以判断原始邮件中是否包含第一扩展信息，如果包含第一扩展信息的话，则可以基于第一扩展信息是否对原始邮件的操作权限的控制。
作为一种可选的实施例，发送端为原始邮件添加第一扩展信息，具体步骤包括：发送端在原始邮件中植入第一功能字段；发送端为第一功能字段赋值，其中，第一功能字段被赋予的值不同，接收端对原始邮件的操作权限就会不同。
具体的，如果第一功能字段的赋值为第一预设值，则接收端对原始邮件的操作权限为禁止转发；和/或，如果第一功能字段的赋值为第二预设值，则接收端对所述原始邮件的操作权限为禁止回信。
具体在本实施例中，举例说明：在原始邮件中植入的第一功能字段为XX-CanNotXX，如果XX-CanNotXX值为0(当然还可以为其他值，例如:00、10等等)，则接收端对原始邮件的操作权限为禁止转发，则接收端针对原始邮件不提供转发的操作权限，此时第一扩展信息中的第一预设内容为第一功能字段被赋予的第一预设值(例如：0、00、10等等)；如果XX-CanNotXX值为1(当然还可以为其他值，例如：01、11等等)，则接收端对所述原始邮件的操作权限为禁止回信，从而接收端针对原始邮件不提供回复、全部回复的操作功能，此时第一扩展信息中的第一预设内容为第一功能字段被赋予的第二预设值(例如：1、01、11等等)；如果XX-CanNotXX值为0/1(当然还可以为其他值，例如：00/01、10/11等等)，则接收端对原始邮件的操作权限为禁止回信和禁止转发，从而接收端针对原始邮件不提供转发、回复、全部回复的操作功能；如果XX-CanNotXX值为2(当然还可以为其他值，例如：110、111等等)，则接收端对所述原始邮件的操作权限例如为禁止转发和仅可对发信人回信，则接收端在回信时不会带上原始邮件的正文，此时接收端不提供转发和全部回复的操作功能，但提供回复的操作功能。
作为另一种可选的实施例，发送端为原始邮件添加第一扩展信息，具体步骤包括：发送端为原始邮件添加第一功能标记，基于接收端所接收到的原始邮件中是否存在第一功能标记，接收端对原始邮件的操作权限不同。
具体在本实施例中，举例说明：发送端为原始邮件添加第一功能标记，第一功能标记例如为XX-CanNotFW、XX-CanNotRE(当然也可以为其他功能标识)等等，进而接收端在接收到邮件之后，可以判断邮件中是否包含第一功能标记，进而确定对原始邮件的操作权限。
进一步的，依据在原始邮件中是否存在具体的第一功能标记，来控制接收端对原始邮件的操作权限是禁止转发，和/或，禁止回信。
具体在本实施例中，举例说明：可以针对转发权限和回复权限设置不同的第一功能字段，例如：发送端为原始邮件添加的第一功能标记为：XX-CanNotFW，则接收端对原始邮件的操作权限为禁止转发，且接收端不提供转发的操作功能；如果发送端为原始邮件添加的第一功能标记为：XX-CanNotRE，则接收端对原始邮件的操作权限为禁止回复，从而接收端不提供回复、全部回复的操作功能；如果发送端为原始邮件添加的第一功能标记为：XX-CanNotRE&FW，则接收端对原始邮件的操作权限为禁止回复和禁止转发，则接收端对原始邮件的操作权限为禁止回信和禁止转发，从而接收端不提供转发、回复、全部回复的操作功能。当然以上第一功能字段与操作权限的对应关系仅仅为举例，并不作为限制。在上述方案中，第一预设内容(或者第二预设内容)则为第一功能字段。
由于在上述方案中，针对原始邮件只需要赋予第一功能字段，就可以实现接收端对原始邮件操作权限的控制，而不需要多次操作，故而降低了发送端的处理负担。
进一步的，如果接收端对原始邮件的操作权限为禁止转发，则在接收端给出用于提示禁止转发的第一提示信息；和/或，
如果接收端对原始邮件的操作权限为禁止回信，则在接收端给出用于提示禁止回信的第二提示信息。
具体在本实施例中，举例说明：第一提示信息(或者第二提示信息)例如为：文字、图片、声音等等，接收端可以确定出接收端对原始邮件的操作权限为禁止转发之后，直接在原始邮件中添加第一提示信息(或者第二提示信息)，进而接收端直接读取处理后的原始邮件中的第一提示信息(或者第二提示信息)并输出该第一提示信息(或者第二提示信息)；又或者，接收端仅仅为原始邮件添加对应的第一扩展信息，接收端在接收到处理后的原始邮件之后，如果解析出对原始邮件的操作权限为禁止转发，则产生第一提示信息并输出；如果解析出对原始邮件的操作权限为禁止回复，则产生第二提示信息并输出等等。
接收端可以以弹出提示窗口的形式输出第一提示信息(或者第二提示信息)、或者在接收邮件正文以水印形式显示等，具体显示方式本发明不做具体限制。
由于在上述方案中，接收端针对对应的操作权限可以产生提示信息(第一提示信息或第二提示信息)，故而能够防止接收端的用户产生无用的操作，以提高对邮件操作的效率。
作为另一种可选的实施例，发送端为原始邮件添加第一扩展信息，从而获得处理后的原始邮件，具体包括：
发送端将原始邮件打包成新的邮件的附件；
发送端为新的邮件添加第一扩展信息，进而获得处理后的原始邮件。
其中，所述附件可以为任意格式的附件，例如：压缩文件、邮件等等，作为一种可选的实施例，为了进一步的提高原始邮件的安全等级，所述附件为通过加密打包方式生成的邮件，从而在接收端得知该附件的密码的情况下，才能够解析获得该原始邮件。
具体在本实施例中，举例说明：所述打包后的附件为data.360smail格式，包含文件头描述和真正文件内容。
文件头描述：
第1Byte：版本号；
第2、3Byte：加密数据校验值；
第4—99Byte：暂空。
真正文件内容：
100Byte之后：真正加密邮件的数据文件。
例如，可以采用对称加密算法对邮件的数据文件内容EML进行加密，加密强度AES256。
作为一种可选的实施例，若所述接收端的邮件接收系统为指定邮件系统，则所述接收端可以获得所述附件中所包含的原始邮件；若接收端的邮件接收系统不是所述指定邮件系统，则接收端无法获得所述附件中所包含的原始邮件。
举例来说，无法获得附件中所包含的原始邮件例如为：接收端无法下载附件、接收端虽然能够下载附件但是无法解析该原始邮件等等。该指定邮件系统可以为与发送端邮件接收系统相同的邮件系统，也可以为发送端选择的任意邮件系统，例如：发送端的邮件系统为360邮件系统，360邮件系统自行设定对邮件解码的特殊格式，发送端将原始邮件处理为该特殊格式之后，作为新的邮件的附件形式发送至接收端；接收端接收到处理后的原始邮件之后，如果判断出其邮件接收系统并非360邮件系统，则控制接收端无法下载附件；又或者，接收端可以读取出特殊格式的原始邮件，如果接收端同为360邮件系统，则其可以解析原始邮件，如果接收端不为360邮件系统，则接收端不能够解析原始邮件。
由于在上述方案中，指定邮件系统才能够获得原始邮件中所包含的附件，故而进一步的提高了原始邮件传播的安全性。
作为一种可选的实施例，若所述接收端非所述指定邮件系统，则所述接收端在获得处理后的所述原始邮件之后提供第三提示信息，所述第三提示信息用于指示所述接收端使用所述指定邮件系统。
具体在本实施例中，举例说明：第三提示信息可以为文字、图像、音频等等，其中，如果第三提示信息为文字或者图像，则第三提示信息以在接收邮件的客户端弹出提示窗口的形式来显示，或者在接收邮件正文以水印形式显示等，例如：如果发送端设置只有360邮件系统能够解析原始邮件，则接收端在获得处理后的原始邮件之后，如果发送当前邮件接收系统并非360邮件系统，则可以通过弹出窗口产生以下第三提示信息“请使用360邮件系统解析该附件”，当然，对于第三提示信息的具体显示方式本发明不做具体限制。
进一步的，S102步骤中，处理后的原始邮件中还包括：第二扩展信息，所述第 二扩展信息用于控制所述原始邮件的失效时间。
具体在本实施例中，举例说明：第二扩展信息可以添加于原始邮件的邮件头、邮件体等区域。
通过上述方案，能够对邮件的失效时间进行有效控制，从而进一步的提高邮件传播的安全性。
作为一种可选实施例，所述第二扩展信息为第二功能字段，若所述第二功能字段的值包含时间点，则所述原始邮件在所述时间点后失效；若所述第二功能字段的值不包含所述时间点，则所述原始邮件不会失效。例如，在具体实施例中，所述第二功能字段为XX-LoseEfficacy，设值为:Tue,10Feb 2015 15:36:57+0800，这表示原始邮件的失效时间为2015年2月10日15:36:57，如果当前浏览邮件的时间已经超出了所述的失效时间2015年2月10日15:36:57，那么原始邮件将失效，将无法正常浏览。否则，如果第二功能字段的值为空，则代表原始邮件不受失效时间控制，所述原始邮件可以被无限期的浏览。
作为另一种可选实施例，所述第二扩展信息为第二功能标记，若所述接收端所获得原始邮件中包含所述第二功能标记，则所述原始邮件在预设时间段之后失效；若所述接收端所获得的原始邮件中不包含所述第二功能标记，则所述原始邮件不会失效。其中，所述预设时间段可以由用户在发送邮件时手动设置，也可以由系统自动设置生成，如系统设置为邮件发送时间开始的2个月后为失效时间，这里的预设时间的具体实现形式不做限制。例如，在具体实施例中，若在原始邮件中添加第二功能标记为XX-LoseEfficacy，且系统设置的失效时间为发送时间开始1个月后，而发送时间为2016年1月1日10点1分，那么到2016年2月1日10点1分就为原始邮件的失效时间点，若当前阅读时间已超过该失效时间，那么原始邮件就已经失效，将不能再被阅读。
通过上述方案，可以针对邮件批量设置失效时间，由此提高了对失效时间设置的效率。
接下来执行S103步骤，发送端将处理后的原始邮件发送至接收端，以供接收端基于所述第一扩展信息实现对所述原始邮件的操作权限的控制。具体的，发送端将处理后的原始邮件，即添加了第一扩展信息的原始邮件发送到接收端后，接收端基于第一扩展信息的具体情况来实现对原始邮件的操作权限的控制，具体实现方法将在后面内容中详细描述。
请参考图2，根据本发明的另一个方面，还提供了一种邮件控制方法，包括：
S201：接收端接收发送端发送的邮件；
S202：所述接收端读取所述邮件中所由所述发送端添加的第一扩展信息；
S203：所述接收端根据所述第一扩展信息实现对所述邮件的操作权限的控制。
下面，结合图2详细介绍本邮件控制方法的具体实现步骤：
步骤S201，接收端接收发送端发送的邮件；这里的原始邮件的邮件格式为MIMO格式，由邮件头和邮件体两大部分组成，邮件头包含了发件人、收件人、主题、时间、MIME版本、邮件内容的类型等重要信息，其中原始邮件的邮件内容包含文本、图像、声音、以及各种附件格式等。
然后执行步骤S202，所述接收端读取所述邮件中由所述发送端添加的第一扩展信息；
其中，在本申请实施例中，接收端读取所述邮件中由所述发送端添加的第一扩展信息用于控制接收端对原始邮件进行转发和/或回信的操作权限，例如：通过第一扩展信息控制接收端对原始邮件禁止转发、禁止回信、禁止转发且禁止回信等等。需要说明的是，第一扩展信息还可用于限制接收端对接收邮件进行存档、打印等日常邮件客户端可见的操作权限，本发明中不做限制。
作为一种可选的实施例，如果所述第一扩展信息中包含第一预设内容，则所述接收端对所述原始邮件的操作权限为禁止转发；和/或，如果所述第一扩展信息中包含第二预设内容，则所述接收端对所述原始邮件的操作权限为禁止回信。
其中，第一扩展信息可以包含多种扩展信息，例如：第一功能字段、第一功能标记等等，基于第一扩展信息不同导致第一预设内容(或者第二预设内容)也不同，对于第一预设内容(或者第二预设内容)为何种内容将在后续进行介绍。接收端在接收到处理后的原始邮件之后，可以判断原始邮件中是否包含第一扩展信息，如果包含第一扩展信息的话，则可以基于第一扩展信息是否对原始邮件的操作权限的控制。
作为一种可选的实施例，接收端读取所述发送端为原始邮件添加第一扩展信息为发送端在原始邮件中植入的第一功能字段；第一功能字段由发送端赋值，其中，第一功能字段被赋予的值不同，接收端对原始邮件的操作权限就会不同。
具体的，如果第一功能字段的赋值为第一预设值，则接收端对原始邮件的操作权限为禁止转发；和/或，如果第一功能字段的赋值为第二预设值，则接收端对所述原始邮件的操作权限为禁止回信。
具体在本实施例中，举例说明：在原始邮件中植入的第一功能字段为XX-CanNotXX，如果XX-CanNotXX值为0(当然还可以为其他值，例如:00、10等等)，则接收端对原始邮件的操作权限为禁止转发，则接收端针对原始邮件不提供转发的操作权限，此时第一扩展信息中的第一预设内容为第一功能字段被赋予的第一预设值(例如：0、00、10等等)；如果XX-CanNotXX值为1(当然还可以为其他值，例如：01、11等等)，则接收端对所述原始邮件的操作权限为禁止回信，从而接收端针对原始邮件不提供回复、全部回复的操作功能，此时第一扩展信息中的第一预设内容为第一功能字段被赋予的第二预设值(例如：1、01、11等等)；如果XX-CanNotXX值为0/1(当然还可以为其他值，例如：00/01、10/11等等)，则接收端对原始邮件的操作权限为禁止回信和禁止转发，从而接收端针对原始邮件不提供转发、回复、全部回复的操作功能；如果XX-CanNotXX值为2(当然还可以为其他值，例如：110、111等等)，则接收端对所述原始邮件的操作权限例如为禁止转发和仅可对发信人回信，则接收端在回信时不会带上原始邮件的正文，此时接收端不提供转发和全部回复的操作功能，但提供回复的操作功能。
作为另一种可选的实施例，接收端读取发送端为原始邮件添加的第一扩展信息为发送端为原始邮件添加第一功能标记，基于接收端所接收到的原始邮件中是否存在第一功能标记，接收端对原始邮件的操作权限不同。
具体在本实施例中，举例说明：发送端为原始邮件添加第一功能标记例如为XX-CanNotFW、XX-CanNotRE(当然也可以为其他功能标识)等等，进而接收端在接收到邮件之后，可以判断邮件中是否包含第一功能标记，进而确定对原始邮件的操作权限。
进一步的，依据在原始邮件中是否存在具体的第一功能标记，来控制接收端对原始邮件的操作权限是禁止转发，和/或，禁止回信。
具体在本实施例中，举例说明：可以针对转发权限和回复权限设置不同的第一功能字段，例如：发送端为原始邮件添加的第一功能标记为：XX-CanNotFW，则接收端对原始邮件的操作权限为禁止转发，且接收端不提供转发的操作功能；如果发送端为原始邮件添加的第一功能标记为：XX-CanNotRE，则接收端对原始邮件的操作权限为禁止回复，从而接收端不提供回复、全部回复的操作功能；如果发送端为原始邮件添加的第一功能标记为：XX-CanNotRE&FW，则接收端对原始邮件的操作权限为禁止回复和禁止转发，则接收端对原始邮件的操作权限为禁止回信和禁止转发，从而接收端不提供转发、回复、全部回复的操作功能。当然以上第一功能字段与操作权限的对应关系仅仅为举例，并不作为限制。在上述方案中，第一预设内容(或者第二预设内容)则为第一功能字段。
由于在上述方案中，针对原始邮件只需要赋予第一功能字段，就可以实现接收端对原始邮件操作权限的控制，而不需要多次操作，故而降低了发送端的处理负担。
进一步的，如果接收端对原始邮件的操作权限为禁止转发，则在接收端给出用于提示禁止转发的第一提示信息；和/或，
如果接收端对原始邮件的操作权限为禁止回信，则在接收端给出用于提示禁止回信的第二提示信息。
具体在本实施例中，举例说明：第一提示信息(或者第二提示信息)例如为：文字、图片、声音等等，接收端可以确定出接收端对原始邮件的操作权限为禁止转发之后，直接在原始邮件中添加第一提示信息(或者第二提示信息)，进而接收端直接读取处理后的原始邮件中的第一提示信息(或者第二提示信息)并输出该第一提示信息(或者第二提示信息)；又或者，接收端仅仅为原始邮件添加对应的第一扩展信息，接收端在接收到处理后的原始邮件之后，如果解析出对原始邮件的操作权限为禁止转发，则产生第一提示信息并输出；如果解析出对原始邮件的操作权限为禁止回复，则产生第二提示信息并输出等等。
接收端可以以弹出提示窗口的形式输出第一提示信息(或者第二提示信息)、或者在接收邮件正文以水印形式显示等，具体显示方式本发明不做具体限制。
由于在上述方案中，接收端针对对应的操作权限可以产生提示信息(第一提示信息或第二提示信息)，故而能够防止接收端的用户产生无用的操作，以提高对邮件操作的效率。
作为另一种可选的实施例，接收端读取的是发送端将原始邮件打包成新的邮件的附件并在新的邮件添加的第一扩展信息。
其中，所述附件可以为任意格式的附件，例如：压缩文件、邮件等等，作为一种可选的实施例，为了进一步的提高原始邮件的安全等级，所述附件为通过加密打 包方式生成的邮件，从而在接收端得知该附件的密码的情况下，才能够解析获得该原始邮件。
具体在本实施例中，举例说明：所述打包后的附件为data.360smail格式，包含文件头描述和真正文件内容。
文件头描述：
第1Byte：版本号；
第2、3Byte：加密数据校验值；
第4—99Byte：暂空。
真正文件内容：
100Byte之后：真正加密邮件的数据文件。
例如，可以采用对称加密算法对邮件的数据文件内容EML进行加密，加密强度AES256。
作为一种可选的实施例，若所述接收端的邮件接收系统为指定邮件系统，则所述接收端可以获得所述附件中所包含的原始邮件；若接收端的邮件接收系统不是所述指定邮件系统，则接收端无法获得所述附件中所包含的原始邮件。
举例来说，无法获得附件中所包含的原始邮件例如为：接收端无法下载附件、接收端虽然能够下载附件但是无法解析该原始邮件等等。该指定邮件系统可以为与发送端邮件接收系统相同的邮件系统，也可以为发送端选择的任意邮件系统，例如：发送端的邮件系统为360邮件系统，360邮件系统自行设定对邮件解码的特殊格式，发送端将原始邮件处理为该特殊格式之后，作为新的邮件的附件形式发送至接收端；接收端接收到处理后的原始邮件之后，如果判断出其邮件接收系统并非360邮件系统，则控制接收端无法下载附件；又或者，接收端可以读取出特殊格式的原始邮件，如果接收端同为360邮件系统，则其可以解析原始邮件，如果接收端不为360邮件系统，则接收端不能够解析原始邮件。
由于在上述方案中，指定邮件系统才能够获得原始邮件中所包含的附件，故而进一步的提高了原始邮件传播的安全性。
作为一种可选的实施例，若所述接收端非所述指定邮件系统，则所述接收端在获得处理后的所述原始邮件之后提供第三提示信息，所述第三提示信息用于指示所述接收端使用所述指定邮件系统。
具体在本实施例中，举例说明：第三提示信息可以为文字、图像、音频等等，其中，如果第三提示信息为文字或者图像，则第三提示信息以在接收邮件的客户端弹出提示窗口的形式来显示，或者在接收邮件正文以水印形式显示等，例如：如果发送端设置只有360邮件系统能够解析原始邮件，则接收端在获得处理后的原始邮件之后，如果发送当前邮件接收系统并非360邮件系统，则可以通过弹出窗口产生以下第三提示信息“请使用360邮件系统解析该附件”，当然，对于第三提示信息的具体显示方式本发明不做具体限制。
进一步的，S202步骤中，接收端从所述邮件中读取信息还包括第二扩展信息，所述第二扩展信息用于控制所述原始邮件的失效时间。
具体在本实施例中，举例说明：第二扩展信息可以添加于原始邮件的邮件头、 邮件体等区域。
通过上述方案，能够对邮件的失效时间进行有效控制，从而进一步的提高邮件传播的安全性。
作为一种可选实施例，所述第二扩展信息为第二功能字段，若所述第二功能字段的值包含时间点，则所述原始邮件在所述时间点后失效；若所述第二功能字段的值不包含所述时间点，则所述原始邮件不会失效。例如，在具体实施例中，所述第二功能字段为XX-LoseEfficacy，设值为:Tue,10Feb 2015 15:36:57+0800，这表示原始邮件的失效时间为2015年2月10日15:36:57，如果当前浏览邮件的时间已经超出了所述的失效时间2015年2月10日15:36:57，那么原始邮件将失效，将无法正常浏览。否则，如果第二功能字段的值为空，则代表原始邮件不受失效时间控制，所述原始邮件可以被无限期的浏览。
作为另一种可选实施例，所述第二扩展信息为第二功能标记，若所述接收端所获得原始邮件中包含所述第二功能标记，则所述原始邮件在预设时间段之后失效；若所述接收端所获得的原始邮件中不包含所述第二功能标记，则所述原始邮件不会失效。其中，所述预设时间段可以由用户在发送邮件时手动设置，也可以由系统自动设置生成，如系统设置为邮件发送时间开始的2个月后为失效时间，这里的预设时间的具体实现形式不做限制。例如，在具体实施例中，若在原始邮件中添加第二功能标记为XX-LoseEfficacy，且系统设置的失效时间为发送时间开始1个月后，而发送时间为2016年1月1日10点1分，那么到2016年2月1日10点1分就为原始邮件的失效时间点，若当前阅读时间已超过该失效时间，那么原始邮件就已经失效，将不能再被阅读。通过上述方案，可以针对邮件批量设置失效时间，由此提高了对失效时间设置的效率。
接下来执行步骤S203，所述接收端根据所述第一扩展信息实现对所述邮件的操作权限的控制。

本申请实施例中提供的技术方案，至少具有如下技术效果或优点：
根据本发明的邮件发送方法，在发送端发送原始邮件前，需要为所述原始邮件 添加第一扩展信息，之后再发送至接收端，从而接收端在接收到发送端发送的邮件之后，可以基于邮件中所包含的第一扩展信息对实现对原始邮件的操作权限的控制，以此来控制收件人对接收邮件的操作权限，以此来避免邮件接收方可以随意对邮件进行处理的情况，从而达到提高邮件收发安全性的技术效果；
同时，从本发明技术方案实现过程来看，对原始邮件的操作权限是由发送端在原始邮件中添加第一扩展信息来完成的，实现过程中无需邮件服务器的参与，只要接收客户端能识别并提取到第一扩展信息就能实现对接收邮件的操作权限的控制，因此说，本发明技术方案对邮件服务器没有任何限制，只对收发客户端有要求，特定邮件客户端搭配任意服务器均可完成对收件人操作权限的控制，这样使用范围更广，普及率会更高。
