DCC version 1.2.28

Version 1.2.28 of the DCC source is in
http://www.dcc-servers.net/dcc/source/dccd.tar.Z  and
http://www.rhyolite.com/anti-spam/dcc/source/dccd.tar.Z
 
http://www.dcc-servers.net/dcc/CHANGES starts with:
    Reduce the number of msync() system calls, significantly speeding up
	dbclean and dccd on FreeBSD.
    Fix "window" size computation for dccd and dbclean on systems with
	more than 4 GByte of RAM.
    Adjust flooding threshold for greylist dccd.
    Changed the dccifd man page to say that dccifd looks at the first
	Received: header for the sender's IP address if was not provided
	by the dccifd client.
    Remove the recommendation for whitelisting the Habeas Mark from the
	sample dcc_conf file.
    Detect bogus -G args reported by Aleksander Dzierzanowski.

    Use fsync() and msync() on /var/dcc/flod.map in dccd to try to
	get Linux to send the file to the disk.
    Use setsockopt(SO_LINGER) to speed shutdown on FreeBSD.
 

If you have previously installed 1.2.12 or newer, then
/var/dcc/libexec/updatedcc should make it easy to fetch, build, and
install this version.  However, if wget is installed on your system
and you are using version 1.2.20 or earlier, you must first delete
/var/dcc/build/dcc-dccd.tar.Z 
The automatically generated /var/dcc/dcc_conf-new might make it easy
to generate a new dcc_conf file for turning on greylisting.
