I am sorry for delay, but now i find time to play with it...
I reenabled ratelimit in event msg:fail:delivery. I was wrong, it was
not the per_addr, but per_rcpt, but result is the same. As i call it
from nested ACL (acl=), the log is not useful.
AFAIK, the msg:fail:delivery event is called once per failed recipient,
and that is exactly what i want to count -- the failed recipients rate.
Previously i did it by recipient callout, but IMO events are better,
as no separate callout is done (and i cannot use hold in callout, as i
use BATV to modify envelope sender).
I reread the doc about ratelimit, and i found that only per_conn
and per_cmd has not mentioned other ACLs, where they can be used. I
will guess, that that approach was choose before events was
introduced. If that definition can be opposite -- i mean list of ACLs,
where particular option cannot be used, then many of them can be used in
events...
I was success with per_cmd/count=1, but i am not sure if that is right.
I can see right number in ratelimit DB, but i did only basic testing
yet. I guess, that per_conn will not be useful in this case to count
failed recipients, but i am not sure. Can you please confirm that?
I am not sure how to deal with the same failing recipient yet... But
can be unique=$local_part@$domain used there?
