Hi Bodin,
that's because of the blacklists - openser "learns" the failed
destinations (like the 503 replied) and block them for some time (4
minutes) to prevent useless processing.
You can disable this auto-learning for blacklists:
disable_dns_blacklist=yes
regards,
bogdan

I found a part of problem.
it's a call to a IPBX
When there is an unavailability of number then I get this from IPBX :
503 Service Unavailable
That seem to work correctly. But when I recall a number to this IPBX
(same or another number ), openser don't try to call IPBX and only
send it to user :
473 Filtered destination (473/TM)
thank for your light
