Community based measurement of capabilities and availability

摘要

Systems and methods herein monitor the ability of an electronic mail (e-mail) computer server to send and receive e-mail messages to and from e-mail clients of the e-mail computer server. The e-mail computer server provides, to the e-mail clients, updates regarding the ability to send and receive e-mail messages. When the e-mail clients determine that the e-mail computer server is unable to send the e-mail messages, the e-mail clients activate a special software program of instructions. When the program of instructions is active and the e-mail clients then receive an e-mail message from the e-mail computer server, the program of instructions causes those e-mail clients who have received an e-mail message to provide an indication of e-mail receipt to the e-mail computer server. When the e-mail computer server receives this indication of e-mail receipt from the e-mail clients, the e-mail computer server can provide an update to the other e-mail clients that e-mail can now be sent.
