It doesn't appear that postscreen_dnsbl_action is working correctly when set
to "drop".
The manual states "Drop the connection immediately with a 521 SMTP reply" -
but that's not happening. It's still checking the block lists.

Assuming that you don't have multiple conflicting "postscreen_dnsbl_action"
settings in main.cf, you can configure postscreen to log the action
(drop, enforce, etc.) with "postscreen -v".
Commands:
# postconf -F "smtp/inet/command = postscreen -v"
# postfix reload
This will slow down postscreen,

The 521 SMTP reply only happens after checking the block lists. It's not
being dropped immediately like the manually says it should be.

The 521 drop comes *after* the pregreet and DNSBL checks.

Is there a way to set a from address for Postfix automatic messages on
delivery failure?
Could someone update the manual for clarification then?
The manual suggests the connection will close immediately - and that's it.
As is stands now, it makes no mention that it will "Allow other tests to
complete" first.
ignore : Ignore the failure of this test. Allow other tests to complete.

Thanks, but I'm looking for a way to set a default in postfix, not to
