For the record: Using python2 (which is what mailman2 uses): >>> from email.header import Header >>> h = Header('[PATCH v2 08/15] dt-bindings: pwm: renesas,pwm: Include generic pwm schema', maxlinelen=76, header_name='Subject') >>> h.encode() '[PATCH v2 08/15] dt-bindings: pwm: renesas,\n pwm: Include generic pwm schema' This is the inner source of the problem, mailman just does something like: >>> import email >>> a = email.message_from_file(open('message')) >>> open('message-mangled', 'w').write(a.as_string()) So we just have to wait until all mailserver admins migrate away from mailman2. I bet this will happen no later than when Python2 will become EOL. :-\ Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-König | Industrial Linux Solutions | https://www.pengutronix.de/ |
