Hi Folks,
I checked this myself, recursing from the a.root-servers.net machine,
and indeed, the authoratative name servers for the 209.249.29. netblock
are not responding with a forward dns entry for 209.249.29.67
I realize that this is a bit of a quandry since sources.redhat.com
responds for multiple domains, but surely the reverse dns should
resolve to _something_, right?
Let me know if I need to take further action on this.
Kind regards,
Matthew Galgoci

To Whom it May Concern:
Sometime around the second or third week of December, reverse lookups
on gcc.gnu.org started failing and continues to this point:
dig -x 209.249.29.67
; <<>> DiG 9.2.1 <<>> -x 209.249.29.67
;; global options: printcmd

As part of our spam blocking strategy, we have sendmail configured to
reject mail from sites where reverse DNS does not provide a valid
address. As a result, our email subscriptions to some of the gnu
lists did not get through until we temporarily disabled this.
Do you plan to make this a permanent "feature" or was it just an
oversite? Our needing to disable that checking in sendmail has meant
that our spam receipts have tripled.
Regards,
M.

You should communicate with Nate Golink on this. He was tracking this
problem down last week and I sent him pertinent email from above.net.

I noticed this has been fixed now, thanks!
Gerald
PS: admin@dbai, you can now remove the exception for 209.249.29.67 in
our sendmail config.
