SPF Inquiry

Hello,

I am just wondering if anyone can clarify how to setup an spf record (I can use the tool at openspf.org to create it). Basically where does the SPF record have to be setup.

Here is the setup

mydomain.com -> hosted with a hosting company on their servers

mail.mydomain.com -> mx record pointing to my hmail server


So, do I get my hosting company to add the SPF record (I don't have an option for this in the hosting control panel) .... or do I set the SPF up somewhere else?

Man, I feel braindead... long week. Thanks for any help.
:)

if you do not control your DNS records then ask your provider to add it for you.

I did ask them... but they assured me that SPF was setup for their mail server.... totally missed the fact that I specifically told them I am not using theirs..

SIGH.. maybe it's time to switch providers


So from what you said.. the domain mydomain.com controls the SPF record and the isp that the mail server is on does not?

That's correct. whoever hosts your domain will control your DNS records.

godaddy lets you create your own spf text records...

and its cheap to switch...


i recently switched 50 domains over...

Sorry to bump.

If I'm using an SMTP relayer in hMailServer, do I need to worry about whether my DNS SPF is setup correctly?

I think that you will have to add the server that you are using as a relay to your sfp records.

yes, if you use a relay your dns will sometimes be queried for SPF to check if that relay is authorized to send mail on your behalf. You can add the fully qualified name and ip address. You will have to add entries for all the servers you relay through.

"v=spf1 a mx -all a:mail.myhoster.com a:256.1.1.1"

Once updated (your isps dns may be lazy, wait at least 24hrs), then check the results here: http://www.seoconsultants.com/tools/spf/ put your email address and the ip of your hosters mail server.

You can also send an email to: check-auth@verifier.port25.com it will bounce back with the results.

btw I hate SPF and I have it turned off in hMailServer

So where do I add the information to make mail coming from my server, going through an STMP relayer (I was having issues with mail bouncing back because of my dynamic IP), valid SPF? My NS is handled by 1and1.com and hostname by Godaddy. But I don't see the option on either of their pages.

Thanks.

SPF is added as a 'TXT' record to your DNS Zone. Many hosting services only give you a small amount of 'A' and 'MX' records you can add. 'TXT' is a little more advanced and the hosters may not have a web interface for such additions, however they should be willing to add it manually for you.

the 'TXT' record should contain eg
v=spf1 a mx -all a:mail.myhoster.com a:256.1.1.1
