The blocking list at dnsbl.net.au has announced it is winding down. As noted in a February 25, 2009 posting on its website, "Please note that as of Wednesday, April 1, 2009 the DNSBL.NET.AU blacklist will cease to exist."
As of this writing on April 29th, 2009, I do still see active entries when querying via DNS, but I assume that these are likely to go away soon. If you utilize this list, I'd recommend removing it from your MTA or spam filter configuration.

Status of DSBL: DEAD
The DNSBL called "DSBL" is no more. As of March 11, 2009, their website reports: "DSBL is GONE and highly unlikely to return. Please remove it from your mail server configuration."
Shutting Down Blocklists
As I often do, today I'm receiving reports about a DNSBL (which I've previously warned was dead) is returning false positive entries for those still using it today.
What does this mean?

Security Sage Update
It seems today as though the Security Sage domains have expired and/or replaced by "placeholder" pages by their registrar. Net result: Bad things. If you were still using their BL, you're probably having problems receiving inbound mail right about now.
DSBL Current Status: DEAD
DSBL, the Distributed Sender Blackhole List, seems to have gone missing. The list appears to have been in operation since at least May, 2002.
