Abstract

A result e-mail (e1) is produced from a received secure e-mail (e) by decrypting (21) the body portion (18) of the received e-mail (e), and providing unencrypted header information (Hu'(16)) from the body portion (18) of the received e-mail (e) in the header portion (Hu(16)) of the received e-mail (e), thereby producing a header portion (Hu(16)) of the result e-mail (e1). The body portion (18) of the received e-mail (e) can then be encrypted (25), thereby producing a body portion (18) of the result e-mail (e1). The result e-mail (e1) can then be used by an e-mail client (5) for summarizing (17A), searching (17D), threading (17B), sorting (17C), etc. Also, encrypted header information (HE(16A)) can be provided in the header portion (16) of a secure e-mail (e), and the header portion (16) can be transmitted, without its corresponding body portion (18), over an air interface to a destination. The encrypted header information can be decrypted (17E) at the destination, and used to decide whether the body portion (18) should be transmitted. In any event, the decrypted header information (Hu(16)) can be used for the aforementioned e-mail client operations.
