we currently use a RTE (Reliable Transport Engine) to send emails

clients such as Web mail clients (www.excite.com, www.free.fr, etc.)
By comparing SMTP headers sent by our RTE and those sent by Mutt on
Linux, I have noticed that the former
That should be MIME headers.
sends "attachment" headers which don't contain the attachments' contents :
Content-Disposition: attachment; filename="test.txt"
There shouldn't be a new line before the Content-Type line. There
file content was not "attached" in this version.
Does anyone know how to force RTEs or MTAs such as sendmail to send
"attachment" headers of the second kind?
This is not a MTA or sendmail problem. Sendmail doesn't send
"attachment" headers. Your RTE may not be formatting the message
correctly before sending it to the MTA. Refer to MIME for how the
message body should be formatted.
