However if I search at https://www.spamhaus.org/lookup/ I see:
104.250.154.20 is listed in the SBL, in the following records:
SBLCSS 104.250.154.20 is not listed in the PBL 104.250.154.20 is not listed in the XBL
And if you follow the SBLCSS link, it's generic and not particularly helpful.
Exactly
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.
No on DKIM. Evidently Postfix and DKIM are not playing nicely on FreeBSD and would take some hacking. I may switch to Exim where DKIM support is easy to configure.
Yes on MTA identification: # telnet localhost 25 Trying 10.0.250.37... Connected to localhost. Escape character is '^]'. 220 lists.c2.social ESMTP Postfix
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., <https://support.google.com/mail/answer/81126>
Google is not blocking our mails. It's Yahoo, Comcast, gmx, etc. They seem to rely on Spamhaus.
I'm thinking this may be because the domain is brand new. Teach me to "volunteer" my time for an organization.
