With "postscreen_blacklist_action = enforce", postscreen logs DNSBL
rejects as "550 5.7.1 Service unavailable...".
With "soft_bounce = yes", postscreen will replace the status with
"450 4.7.1" before it sends the reply to the SMTP client.
If your postscreen logs DNSBL rejects as 4XX then some unhelpful
person has changed the source code and I cab't help you with that.
