Abstract: Embodiments are disclosed for distributing email delivery processing. In some embodiments, an inactivity indicator associated with a user agent is detected. Based on the inactivity indicator, a delivery completion request is generated and sent to a first sending user agent from which a first email is received prior to detecting the inactivity indicator. The delivery completion request includes an identifier for the first email and one or more selectable delivery options including at least a delivery termination option. In response to a reply from the first sender user agent to the delivery completion request that includes selection of the delivery termination option, delivery of the first email to the first user agent is terminated.
