+
+ Feature: Base 32 encoder/decoder per RFC 4648. This code
+ was going to be used for long queue IDs, but plans were
+ changed. Files: src/util/base32_code.[hc].
+
+20110313
+
+ Bugfix (introduced Postfix 2.8): number the postscreen DNSBL
+ requests, so that delayed results for an old session are
+ not added to the score when the same remote SMTP client has
+ reconnected in the mean time. Files: postscreen/postscreen_dnsbl.c,
+ dnsblog/dnsblog.c.
+
+ Cleanup: protocol description in dnsblog(8) manpage. File:
+ dnsblog/dnsblog.c.
If you upgrade from Postfix 2.7 or earlier, read RELEASE_NOTES-2.8
before proceeding.
+Incompatible changes with snapshot 20110313
+===========================================
+
+Use "postfix reload" after "make upgrade" on a running Postfix
+system. This is needed because the protocol between postscreen(8)
+and dnsblog(8) has changed.
+
+Major changes with snapshot 20110228
+====================================
+
+postscreen(8) support to force remote SMTP clients to implement
+proper MX lookup policy. By listening on both primary and backup
+MX addresses, postscreen(8) can deny the temporary whitelist status
+to clients that connect only to backup MX hosts, and prevent them
+from talking to a Postfix SMTP server process.
+
+Example: when 1.2.3.4 is a local backup IP address, specify
+"postscreen_whitelist_interfaces = !1.2.3.4 static:all".
+
Incompatible changes with snapshot 20110219
===========================================
Don't forget Apple's code donation for fetching mail from
IMAP server.
+ Use queue ID (file name) based on inode number and enough
+ (time or random) bits to avoid repetition in 10+ years.
+
+ Simplify postscreen logic: set the noforward flag if the
+ client made an unforgivable error. Individual "fail" flags
+ are needed only to avoid logging the same offense multiple
+ times. Individual "pass" flags are still needed as proof
+ that the client didn't skip tests by hanging up early.
+
postconf command-line option to show the compile-time
settings (CCARGS, AUXLIBS) in case binary packages
don't install the makedefs.out file.

+/* DESCRIPTION
+/* base32_encode() takes a block of len bytes and encodes it as one

+/*
+/* base32_decode() performs the opposite transformation. The result
