The Microsoft Internet Mail Connector (IMC) supports the Multipurpose
Internet Message Extentions (MIME) standard. This allows the IMC to send
and receive messages with attachments to and from other MIME compliant
systems.
The IMC is compliant with RFC 1521 "MIME (Multipurpose Internet Mail
Extensions) Part One: Mechanisms for Specifying and Describing the Format
of Internet Message Bodies." This RFC document sets standards for the
format of message bodies to allow multi-part textual and non-textual
message bodies to be represented and exchanged without loss of information.
As per this RFC, the IMC expects messages received from the Internet to
specify attachment filenames using the "filename=" parameter on the
"Content-Type" MIME header. The IMC also uses this format to specify
attachment filenames when sending out messages containing attachments.
The IMC also recognizes the "Content-Disposition" MIME header and can read
attachment filenames in incoming messages if they are specified with this
header. However, the IMC will not use this header when sending messages out
to the Internet.
