and I think I know why that happened:
my today's message to the list was suddently accepted, and looking at
the headers I noticed
X-SenderScore: 4
so I had to start digging...
turns out a user on my server had sent an email to a contact using a
domain which is no longer active at fastmail, and fastmail -- instead of
giving 5xx -- gave 4xx and made my server keep retrying, and each
delivery attempt (to each IP address of each MX every time) would make
score worse.... but when retry rules increased period between retries,
score went a bit up -- to 4, which I understand is still _very_ bad...

Hi there
I'm (mostly) new to OpenSMTPD (5-10 line quick configs do not count),
having used Exim for 20+ years, and finally finding motivation to
replace (parts of) my setup with something more compartmentalized.
Trying to subscribe to the list (by sending message to
misc+subscr...@opensmtpd.org), I received a very brief message saying
550 message rejected
My initial reaction was that subscription instructions do not work, but
after trying to route the request via a different server, I managed to
subscribe.
It's kind of funny that first time I experience a permanent error based
on ISP reputation is when trying to subscribe to the list, but at least
may I suggest making rejection message more helpful.
For reference, here's line from my logs:
Oct 3 17:27:01 chroot smtpd[21929]: 70b9b7d3b34130cf mta delivery
evpid=3c1648572a668f57 from=<k...@krot.org>
to=<misc+subscr...@opensmtpd.org> rcpt=<-> source="5.9.155.110"
relay="95.179.212.215 (mx-in.poolp.org)" delay=14s result="PermFail"
stat="550 message rejected"
Greetings!
Kirill
