for an activity with fastapi, I am preparing a Response object with the content of a email.mime.multipart MIMEMultipart object. Adhering to the standards (RFC), a MIMEMultipart response uses CRLF line endings (policy=HTTP). However, the binary attachment I am adding with MIMEApplication() and multipart.attach() in that case gets corrupted since all bytes corresponding to newlines (LF) are replaces with CRLF.
Am I doing something wrong or is this a bug that needs to be fixed?
What I would like to achieve is building a RFC-compliant MIMEMultipart payload in which the subparts do not get altered (in case of application/octet-stream).
Thanks,
Sophonet
