And if you follow the SBLCSS link, it's generic and not particularly
helpful.

It looks like your DNS and SPF are OK. Are you DKIM signing your
outgoing list mail and does your outgoing MTA identify it self as
lists.c2.social? These things can help.

Also, you don't publish a DMARC policy (I don't either), but the lack of
one, even if it would be p=none, can count against you. See, e.g.,
