AT&T's PMX mailer products include a new /bin/mail that uses
Content-Type: and Content-Length: headers to avoid the problem.  Anything
within the Content-Length: characters is the body of the message and
is not parsed for addition header information.  There are several
advantages to this scheme.  If Content-Type: is Multipart, then there
are additional Content-Type:, Content-Length: headers inside of the
first Content-Length: characters, allowing multiple attachments to a
single message.  The Content-Type: field may be used to do format
transformations as required by the receiving system or to note that
the attachment is 8-bit-binary which should not be sent unless the
receiving system is known to handle binary files.  The ability to
attach any type of file to a message with encoding done transparently
if necessary is extremely important in office automation environments.
Any chance of seeing this (or Forms mode) in Mush?
