Message attachment management

A method and a system for exchanging email attachments are disclosed. An attachment can be sent to one or more recipients using a file hosting service. In this way, instead of including the attachment with the email, the attachment is sent and stored on a file server. The attachment can later be retrieved by the email's recipients using a link that is included in the email. The link can be embedded in the email's header or body. In one case, the attachment is automatically retrieved from the file server using the link. In another case, a recipient can manually retrieve the attachment from the file server using the link. A link can be associated with an expiration date such that when a link expires, the link can no longer be used to retrieve the attachment. 本发明公开了用于交换电子邮件附件的方法和系统。可利用文件托管服务向个或多个接收人发送附件。通过这种方式，并非在电子邮件中包括附件，而是发送附件并在文件服务器上存储附件。附件稍晚可以由电子邮件的接收人使用包括在电子邮件中的链接来检索。该链接可嵌入电子邮件的标头或主体中。在种情况下，使用该链接从文件服务器自动检索附件。在另种情况下，接收人可以使用该链接从文件服务器手动检索附件。链接可以与过期日期相关联，使得在链接过期时，该链接不再能够用于检索附件。
