DSBL.org

DSBL's list nameservers have continued to answer queries for 10 months after the list went off. From now on, DSBL list queries (to *.list.dsbl.org, *.multihop.dsbl.org and *.unconfirmed.dsbl.org) will go to the nonexistant nameserver stop-using-dsbl.dsbl.org, which resolves to the unroutable example IP address 192.0.2.1.

This should keep nameservers everywhere working like they should, while slowing down spam filters that are still using DSBL. Hopefully the annoyance of the slowdown will convince the remaining DSBL users to stop using DSBL. DNS timeouts should not cause any email to get lost.

Please stop using DSBL. The list has been empty for almost a year.

It looks like the database can not be recovered from the old hard disks - both disks in the RAID1 array are totally broken. Because we absolutely do not want to lose removal requests, we will not restart the list from an older backup. If the list gets continued (interest has been expressed by several organizations), it will start with an empty database.

As for current DNS queries: all the nameservers for list.dsbl.org are serving an empty zone, which should mean DSBL causes no email to get lost. The rsync server also contains the empty zone files. Any rejections that reference DSBL are likely to be mail servers using an ancient copy of the list, or mail servers that are misconfigured to print out a DSBL error message when in reality another list was queried.

If you are blocked, you may want to check out senderscore to find out which list(s) do block you.

If you are looking for another blocklist to use, the DNSBL statistics page is a good start.

DSBL's old server is gone. A new one is being worked on.

Since the removal mechanism is offline now, the zone files have been temporarily emptied.
