Hi Bind-Users and Devs,
We are running servers which have an IP netmask of 255.255.255.255 and on which
we had configured BIND to "allow-recursion { localnets; };". In this setting I
would expect that only requests from the localhost allow recursion as there is
no localnet. However, BIND allow
Sorry, I forgot to mention that the Servers were running "Windows Server 2008".
Linux does not seem to be affected.

Our email group wants to change the current SPF txt record and replace it with

How can I put it in so that it works correctly?
Thanks

You may take a look at google's setting as samples.
It's just grouping, I.e, gmail's SPF:
$ idig gmail.com txt
gmail.com. 300 IN TXT "v=spf1
redirect=_spf.google.com"
$ idig _spf.google.com txt
_spf.google.com.300 IN TXT "v=spf1
include:_netblocks.
3.1.3. Multiple Strings in a Single DNS record
As defined in RFC 1035 sections 3.3.14 and 3.3, a single text DNS record
(either TXT or SPF RR types) can be composed of more than one string. If a
published record contains multiple strings, then the record MUST be treated as
if those strings are

Hi Steven, Jason, Ged and Bind expert
Thanks for the reply. It is great help.
However, I need ask more.
For this include clause to be added in, I have also need to add DKIM records.

part will use it.

Our secondary DNS machine went down (and unnoticed for 24 hours).
Today, we had multiple people calling about email that hadn't come in, and
trouble with outgoing emails not going out.
Our primary DNS was up the whole time. So my question is, why would my

Hi Jeff,
You've pointed out two separate problems (incoming e-mail not coming in &
outgoing e-mail not going out), so some more details about your environment
would probably be useful here:
- are you combining both authoritative and recursive DNS on the same
servers?
- Are you using different MXe
I agree that the incoming and outgoing are different issues. I just mention it
because I dealt with issues on both fronts today. The few claims that I had
about email not being delivered were proved false by reviewing the logs that
showed they had actually been delivered. So I don't think tha
