Patent attributes
A registered address that is normally used by the user and comprises personal information is input into an MFP apparatus. The MFP apparatus sends a command including the registered address to the mail provider, obtains a new address for which the registered address is designated as a forwarding address, and deletes the registered address from the MFP apparatus. Where the MFP apparatus receives an e-mail non-arrival notification, the MFP apparatus sends the non-arrival notification to the new address. The non-arrival notification sent to the new address is received by the mail provider and forwarded to the registered address. In this way, notification of the e-mail's non-arrival can be provided without the registered address remaining in the MFP apparatus.
