What do you mean by mangled? If you mean that your mails, as
distributed by uknof, come as an email From: the list with your
original email as an attachment inside, then I'd say that is almost
certainly through the DMARC mitigation settings of the list reacting
to your domain's DMARC setting.
It doesn't happen with every email so I don't think it's set to
happen unconditionally. Your DMARC policy for bensley.me is
"quarantine", so I think that is causing the DMARC mitigation of
"wrap_message":

I don't think the list would want to turn off DMARC mitigations
since them people's emails would start being rejected for failing
DMARC.
Is it the wrapping of your mail as an attachment inside a mail from
the list that you particularly do not like? If so then the other
option would be to just change the from address (and not attach
original email), but that loses some information from your original
email.
You could stop using DMARC yourself. 😀
Thanks,
Andy
