[RCD] Why is "From " in the body preceded with a quote character ">" (was: How to fix incorrect CT-declaration "text/x-mail" for .eml attachments?)

From a practical side of view, the still open question for us is: How to

(re)build a fixed magic.mgc which does at least support "Return-Path:", "Return-path:" and "return-path:"?

Besides the original issue: Is it Roundcube or something else that is automatically preceding the string "From " at the beginning of a line with a quote character ">" upon sending?

In know that it must have to do with the mbox specification, but given that we have a header "Content-Length:", this shouldn't be necessary, right?
