LWN emails bouncing due to dnsbl.njabl.org
There are currently a number of sites bouncing emails from LWN.net due to an
alleged listing in the dnsbl.njabl.org blacklist. The only problem is that
this blacklist has
been offline since 2013. That domain has been taken over by somebody
else; checking web content at that address is not recommended as it is, to
put it lightly, non-technical. If you are not getting expected email from
LWN, you might want to look into whether your local setup is still trying
to use that old, discontinued blacklist.
