With the lates snapshot (i386) this is still happening.
After a relay rejects me because of "too many recipients",
my OpenSMTPd disables that route.
Here is the messages for ~120 recipients, accpeted my my OpenSMTPd:

... resulting in the host being "Temporarily disabled"
(to be sure, is that my OpenSMTP disabling this relay,
or the relay temporarily disabling me?):

Eventually, OpenSMTP gives up on that route completely for 800s:
Jan 8 09:19:46 biblio smtpd[28003]: smtp-out: Disabling route [] <->
147.32.232.237 (relay.fit.cvut.cz) for 800s
Jan 8 09:19:46 biblio smtpd[28003]: smtp-out: Closing session
62fe24cfe25a335f: 0 message sent.
As that was my only route, now I cannot send anything, right?
At any rate, it seems the route disabling code is still there.
Thank you for your time
Jan
