Alert email Content Transfer Encoding

New Member

Splunk Enterprise 8.0.2
I can send an email through our enterprise relay using python3 smtplib email.message. These come through with Content Transfer Encoding set to 7bit.
When I setup and trigger an email alert action through Splunk, it fails to relay through and the Content Transfer Encoding is set to base64.
That is the only difference I can detect between the 2 emails using wireshark.
Is there a way to change the Splunk alert email Content transfer encoding to 7bit?
I have looked at and and cannot see where this is specified, it may be in another conf file or perhaps needs to be explicitly defined in one of those 2 .py files?
Thank you for any help.

If you edit both $SplunkHome\etc\apps\search\bin\ and and replace UTF8 with us-ascii, emails are sent with 7bit encoding.
