This message conforms to MIME standards

RFC2045

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. If the SendMimeErrors option (SendMimeErrors) is set, V8 sendmail includes the following header in all returned (bounced) mail:

 MIME-Version: 1.0 

This is hardcoded into sendmail . See the SendMimeErrors option for further details about this header.

The MIME-Version: header should never be declared in the configuration file.
