The MIME Encoding/Decoding library supports the POP3 and SMTP libraries by providing MIME functionality. Applications may not find a need to directly call into this library. However, this library is required for any use of POP3 and SMTP functionality. It is provided as a separate library so that applications needing both POP3 and SMTP support don't have duplicate code built into them.
There is no sample application for the MIME library. However, the MIME library is used invisibly in the POP3 and SMTP sample applications.
