You are right. The milter is called twice, because a FILTER
(spamassassin in this case) is applied, after which the message is
re-injected using pickup, which triggeres the second milter run
during cleanup. (Still, I think the graphic on the MILTER page
could be improved :-))
I guess the best way to combat this would be to use spamassassin
as a milter as well?
This is fine for mail incoming via port 25 from other mail servers.
If you do this for mail from your clients, they will complain that
sending e-mail takes too long (SA scanning may take some time).
Therefore I use post-queue filter for mail received from
internal/authenticated clients.
Or do you have another idea?
(Maybe configuring a special cleanup instance which has
non_smtpd_milters= set for pickup using cleanup_service_name?)

This is usually done by feeding mail from post-queeue filter via
special port where milters are not running via:
-o receive_override_options=no_milters
(usually no_address_mappings too).

I see your point and had a good look at the documentation of both
spamassassin and rspamd: Both only seem to support integration as a
milter, or with delivery to e.g. sendmail command. But no re-injection
via smtp to a local port, which has a smtpd with these options applied
running.
I forgot to mention I use amavisd-new because of these reasons.
To be more precise, when receiving mail from internet on port 25, I prefer
amavisd-milter talking to amavisd so we can reject mail immediately,
while clients from port 465/587 talk to amavisd-new using LMTP and
amavisd-new injects mail back via LMTP on alternative port.
in some networks, even port 25 from LAN goes via LMTP to amavisd-new, and
port 25 from the world is redirected onto other port with postscreen and
milter.
