SPF records (include:spf.rollernet.us) for smtp auth mail

Post by lavajoe »

I ran into an issue today with SPF. I have several domains I am primary DNS for (I use rollernet as secondary), and some of these domains use rollernet for mail (mail hosted accounts), so mail is often sent from, in my example, rollernet's webmail.

I added the SPF record recommended in your FAQ:

v=spf1 include:spf.rollernet.us -all

Since spf.rollernet.us's SPF record is:

v=spf1 ip4:208.79.240.2/32 ip4:208.79.241.2/32 -all

This does not include smtpauth's IP (208.79.240.5), so mail sent from rollernet was getting rejected with a bad SPF match.

I altered my domain's SPF record for these domains to be:

v=spf1 include:spf.rollernet.us a:smtpauth.rollernet.us -all

This fixes it, since it now includes smtpauth.rollernet.us as a sender.

Is this what you recommend? Or should you be including this in your spf.rollernet.us records?

-Thanks, Joe

That'll work too, and we also provide an SPF include of "auth.spf.rollernet.us" that has the IP address of the auth server.

Code: Select all

$ host -t txt auth.spf.rollernet.us
auth.spf.rollernet.us descriptive text "v=spf1 ip4:208.79.240.5/32 -all"
