[issue30032] email module creates base64 output with incorrect line breaks

New submission from Jon Ribbens: The email module, when creating base64-encoded text parts, does not process line breaks correctly - RFC 2045 s6.8 says that line breaks must be converted to CRLF before base64-encoding, and the email module is not doing this. >>> from email.mime.te

[issue30033] email module base64-encodes utf-8 text

Jon Ribbens added the comment: So on further investigation, with the new API and policy=SMTP, it does generate correct base64 output. So I guess on the basis that the new version can generate the right output, and it appears to be a deliberate choice that the default policy breaks the RFCs

[issue30032] email module creates base64 output with incorrect line breaks

Jon Ribbens added the comment: OK cool, but please note that this is a MIME issue not an SMTP issue - if the message has text that is being base64-encoded then it must use CRLF line breaks regardless of whether SMTP is involved
