SMTP attachment

Hi, /prog/, how do you add attachments to an SMTP email header? I know it's using a boundary and 'Content-Disposition' and 'Content-Type', but so far nothing has worked.

You don't send attachments in the header.  You set the content type and boundary in the header then you send the attachments in the body.
