This is exacerbated when the email and file is sent to a distribution list containing a large number of recipients. In addition, this method can leave a sensitive file susceptible to interception during transmission.
The solution is to incorporate a method wherein the email application sends a smaller, initial email prior to sending the main email. The purpose of this initial email it to verify that the recipient's email address still exists.
In a preferred embodiment, when the sender initiates an email that meets certain criteria, the system sends a small preliminary email to each recipient. After a certain amount of time, the system sends the main email to any recipient that has not returned a Delivery Failure Report.

Security level of email
Determination of whether this is an actual failure to deliver or an auto reply can be based on the text in the subject, or, if widely adopted, a set format in the return email could be set.
This solution is different from current art in that the novel system dynamically pings, wher...
