(Without having gone through your testing, and not knowing to which
detail you're familiar with the mail standards, so please excuse is this
is too basic:)
This can possibly boil down to the old e-mail standard for the "mailbox"
format - the old local storage format for incoming mail to a user
(typically in /var/(spool/)mail/liman (in my case). In those files,
messages are separated by a "From ...." line (no colon! not header!),
and in order to not mistake a text line starting with "From " for a
message separator, all "From " lines in a message had to be "quoted",
typically with a ">" leading to text like this:
text text text text text text text text text text
text text text text text text text text text text

Comic Sans font, and I was very upset with my editor ...
Mail user agents typically convert this back to "From ..." when showing
a message, but as you undoubtedly realise, there is ample room for
mistakes here. One bug is to also "quote" lower case "from ..." to
">from ..." or even ">From ...", and/or when converting back make
another mistake ">from ..." --> "From ...".
One way around this could be to see whether you can append your Python
code as something else than "text/plain", and have it encoded in
Quoted-Printable (or even BASE64), which ought to eliminate the
problem. (Q-P encoding would lead to "From ..." --> "=70rom ...", if I
remember the standard correctly, which I probably don't ;-).
Then again, I could be completely off here. I usuaslly am ... ;-)
