S/MIME (Secure/Multipurpose Internet Mail Extensions), described in
[SMIME-MSG], provides a method to send and receive secure MIME
messages. Before using a public key to provide security services, the
S/MIME agent MUST certify that the public key is valid. S/MIME agents
MUST use PKIX certificates to validate public keys as described in the
Internet X.509 Public Key Infrastructure (PKIX) Certificate and CRL
Profile [KEYM]. S/MIME agents MUST meet the S/MIME-specific
requirements documented in this I-D in addition to those stated in
This specification is compatible with the Cryptographic Message Syntax
[CMS] in that it uses the data types defined by CMS. It also inherits
all the varieties of architectures for certificate-based key
management supported by CMS.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
