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

To warm-up an old discussion about this feature:

i think this should be really disabled by default, because of user confusion and possible security issues.
I agree it confuses a bit (maybe because of the lack of docs), but other other hand it is useful as it spears a lot of resources without any deep knowledge from the user. Anyhow, what security issues do you see here?

bogdan
