Setting up SPF Record

Hi I am brand new to SPF and need a little guidence. I see it says "The
record is placed in the DNS tree at the domain name it pertains too".

I am running Bind 8.3.6

So basically I would change

zone "domain.com" IN {
type master;
file "master/domain.com";
allow-transfer {"servers";};
};

To something like this...???


zone "domain.com" IN {
type master;
file "master/domain.com";
"v=spf1 a mx ptr ~all"
allow-transfer {"servers";};
};

TIA,

Shay

Re: Setting up SPF Record [In reply to]

Hi,

You would edit master/domain.com, add something like

@ IN TXT "v=spf1 a mx -all"

which defined the txt record for domain.com
or maybe also

www IN TXT "v=spf1 a mx -all"

to define it on www.domain.com

You should define it on any domain that is explicitly defined in the
zonefile, but don't define IN TXT on any domain that you already have a
cname on.

Also, make sure that the dns zonefiles you are editting are indeed the
authorative zonefiles, ie. that you are not editting some local
zonefiles that are not used on the internet but only on a local dns you
are running.

Kind regards,

Koen

Inbound main is not relevant to SPF for your domain. If
207.8.215.82 is the only server used for outgoing mail for your domain
you can use:

v=spf1 ip4:207.8.215.82 -all

> what I should do with HELO/EHLO

Set up a TXT record for mail.icrsurvey.com and use:

v=spf1 ip4:207.8.215.82 -all

...since that is the only IP for that hostname.
