[New-bugs-announce] [issue12552] email.MIMEText overide BASE64 on TEXT/HTML

[Blame-me Jaillie]

New submission from Blame-me Jaillie <darkshado.1972 at gmail.com>:

Apologies if this is in the wrong place.

Simple enough issue. This line of code from email.mime:

MIMEText(textonly, 'plain', _charset='UTF-8')
Where 'textonly' is just a plain text email message to be displayed on a multipart message in a client that does not support HTML email.

This always results in: Content-Transfer-Encoding: BASE64
rather than allowing selection of the encoder (7 or 8 bit MIME/quoted printable). The option to set this with _encoders was removed.

This presents a couple of issues. First of all, BASE64 is not optimal for text - it adds (granted small) amounts of overhead and CPU usage. Second, commercial and O/S anti-spam scanners have rules that penalise messages solely BASE64 encoded.

As this is part of the mime email package, a simple flag to set the Content-Transfer-Encoding by hand would be help anyone trying to produce sensible email applications with Python.

Whilst my version of Python is old - I believe this issue remains in later versions.
