The message body type is described under
the -B command-line switch (-B). The B line in the
qf file stores whatever the body type was set to,
either from the command line or by the SMTP MAIL command. The two
usual body types are 8BITMIME or
7BIT.
The form of the B line is:
Btype
There must be no space between the B and the
type. If the
type is missing, the body type becomes the
character value zero. If the entire B line is
missing, the default is 7BIT. If
type is longer than MAXNAME as defined in
conf.h (MAX...) when
compiling sendmail, it is truncated to MAXNAME-1
characters when the qf file is read.
Note that the type must be either
7bit or 8bitmime. Anything else
will not be detected when the qf file is read and
might eventually cause the ESMTP dialog to fail:
501 <sender>... Unknown BODY type badtype
This error will be reproduced at every MX site for the recipient
until a site that does not speak ESMTP is found or until the MX list
is exhausted.
