sendmail, 4th Edition

${bodytype}

The ESMTP BODY parameter V8.8 and later

MIME support in V8 sendmail has been coupled to ESMTP of the new BODY parameter for the MAIL From: command. That parameter tells sendmail whether it is dealing with 7-bit or 8-bit MIME data:^[315]

MAIL From:<address> BODY=7BIT
MAIL From:<address> BODY=8BITMIME

The parameter specified for the BODY (BIT or BITMIME) is the value stored in the ${bodytype} macro.

The ${bodytype} macro is intended to be used as part of the delivery agent’s A= equate (A= on page 738). It provides a means to pass this information to delivery agent programs as part of their command lines.

${bodytype} is transient. If defined in the configuration file or in the command line, that definition can be ignored by sendmail. Note that the -B command-line switch (-B on page 232) can be used to specify a value to be stored in ${bodytype}, but only for initial mail submission. Also note that a $& prefix is necessary when you reference this macro in rules (that is, use $&{bodytype}, not ${bodytype}).

^{[315] *} BODY=BINARYMIME might be an option in the future.
