file attachment issue to email? - php

Question

My file is attached and sent with no error, but the attachment in my Inbox folder shows as follows:
// this is included in the email subject and body, so not correct
file attach boundary="==Multipart_Boundary_xb46dc57fb3a58f8a859f39992cfd954ex"
This is a multi-part message in MIME format.
// this is included in the email subject and body, so not correct
--==Multipart_Boundary_xb46dc57fb3a58f8a859f39992cfd954ex
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
// this is included in the email subject and body, so not correct
