1. An electronic device comprising: a memory configured to store a mailer application and a second application, wherein the memory is further configured to store an application management table including information specifying the second application and a memory address indicating a memory area of the memory in which the second application is stored; the memory is further configured to store delivery-trusted source data related to the second application, wherein the delivery-trusted source data is indicative of an electronic message address that is trusted; and a processor in communication with the memory, wherein the processor is configured to execute the mailer application to receive delivery data attached in an electronic message, the processor further configured to compare a source address of the received electronic message with the stored delivery-trusted source data to determine whether delivery of the delivery data is permissible; and in response to determination that at least some portion of the source address corresponds to at least a portion of the delivery-trusted source data, the processor is further configured to deliver the delivery data to the second application; and after delivery of the delivery data to the second application, the processor is further configured to execute the second application stored in the memory area to utilize the delivery data.
