Postfix snapshot 20100916 fixes one tiny buglet in postscreen, and
improves the logging for pregreeting spambots. If nothing else
comes up, this will be the last update in a while.

Bugfix (introduced 20100914): the "postscreen_greet_wait"
delay speedup worked only for DNSBL listed sites. File:
postscreen/postscreen_dnsbl.c.
Workaround: better handling of pregreeting spambots. The
postscreen built-in SMTP engine no longer sends a 220 banner
to a client that falls into the pregeet trap. This eliminates
many "non-SMTP command" records in postscreen logging, as
the SMTP client and server no longer get out of sync. It
also results in better logging of sender/recipient information.
