These are different things. MIMEdefang limits the length of a single
header line, while Sendmail limits the length of the entire header.

Setting confMAX_HEADERS_LENGTH to 8191 would reliably limit the length
of each individual header line to 8191, too, of course, but it would
be a rather drastic way of achieving that. :-)
