Which of the following is not an email encryption security standard?

A. IMAP

B. MOSS

C. PGP

D. PEM

Solution

A. IMAP is associated with email, but it is not an email security standard, it is a protocol to receive email and excels over POP3 when working with mail on multiple devices/clients \\ it also leaves a copy on the server. Although answers B, C, and D are all incorrect, they do specify valid email security standards: MIME Object Security Services (MOSS), Pretty Good Privacy (PGP), and Privacy Enhanced Email (PEM).
