Controlling expiration of electronic mail single store attachments

An electronic mail (e-mail) management system configured for expiration control of e-mail single store attachments, the system comprising:

• a computer system comprising one or more computers each comprising memory and at least one processor;
• a mail server coupled to one or more repositories of mail user databases;
• an attachment server coupled to a repository of single store attachments;
• and,
• e-mail processor logic comprising program code enabled, when executing in the computer system, to receive and copy a new e-mail message in the attachment server, to remove any attachments in the e-mail message and to store the removed attachments in the repository of single store attachments, to replace the removed attachments with a corresponding attachment link to the removed attachments in the repository of single store attachments in order to create a single store linked e-mail message, to assign an expiration date to the removed attachments stored in the repository of single store attachments, each attachment link that is included in an e-mail message comprising a communication mechanism programmed to notify the attachment server that a corresponding attachment is active and that a current expiration date for the for the corresponding attachment should be modified such that the corresponding attachment is not deleted from the single attachment store, and to subsequently notify the attachment server by way of the communication mechanism to adjust the expiration date for the attachment.

A computer program product comprising a computer usable storage medium comprising a memory device embodying computer usable program code for controlling expiration of electronic mail (e-mail) single store attachments, the computer program product comprising:

• computer usable program code for receiving a composed e-mail message intended for delivery to a designated recipient at a designated e-mail address, the e-mail message including an attachment;
• computer usable program code for creating a single store linked e-mail message by removing the attachment from the sent e-mail message and replacing the attachment with a corresponding single store attachment link;
• computer usable program code for storing the removed attachment in an attachment server accessible at the single store attachment link and in association with an expiration date, the single store attachment link that is included in the e-mail message comprising a communication mechanism programmed to notify the attachment server that the removed attachment is active and that a current expiration date for the removed attachment should be modified such that the removed attachment is not deleted from the single attachment store;
• computer usable program code for sending the single store linked e-mail message to the recipient at the designated e-mail address;
• computer usable program code for notifying the attachment server by way of the communication mechanism to adjust the expiration date for the attachment;
• and,
• computer usable program code for deleting the attachment stored on the attachment server subsequent to passage of the expiration date.
