I keep getting disabled on [email protected] mailing list.
I have resubscribed many times. Is there a problem with my
configuration? What can I do to fix this?

You need to stop rejecting mail from the list. That could be because
you've chose strict DMARC enforcement, which is incompatible with
most discussion mailing lists.

you have this one duplicated later.
reject_unknown_reverse_client_hostname,
reject_unknown_client_hostname,
The latter matched the former plus a bit more.
Both aren't needed, people here usually advide only use the first one.
Not even mensioning you have them duplicated as well.
reject_rbl_client zen.spamhaus.org,
reject_rbl_client psbl.surriel.com,
consider using postscreen. You may then need separate exemption for this
list, but that should
permit
Can I add something to make sure that postfix.org emails are not
rejected?
I guess putting:
45.90.5.195 OK
into /usr/local/etc/postfix/client_checks could help. Also
2a03:4000:20:189::195 OK
if you have ipv6 configured.
...do you use any milters? Any mail gateways in front of your server?
Can you check IPs listed above in your logs, if you rejected mail from them?
