sendmail, 4th Edition

MIME Headers

MIME is documented in RFC2045, RFC2046, RFC2047, RFC2048, and RFC2049. The sendmail program cares about MIME only when bouncing messages and when determining how to convert the message body between 8 and 7 bits. Those MIME headers for which sendmail contains special knowledge are shown in Table 25-11.
