Hello everyone,

This is my first time posting here, and I'm not sure if it's the right place or not to ask my question. This is a general DNS question, specifically, I think, SPF.

(Btw, I do use Bind in my system, so that's why I'm here.)

I host email using SmarterMail, and all 400+ customers either use a regular email client (desktop app/mobile device) or the webmail interface.

One particular customer wants to use Gmail as their email client for sending email from their domain. I helped set up the settings at gmail for the SMTP server, and did the google-siteverification and added _include:gmail.com_ to the SPF TXT record, as well as DKIM and DMARC configured. I get green lights for the domain from Dmarcian (well, they said I had a duplicate SPF value, which I have removed).

The emails that get sent *do* arrive for other users on my email server, but *not* to email addresses off-server, ie; @live.com

I can see the traffic from gmail in my logs, and it appears the emails are sent, but they do not arrive.

Stumped. Any spare brain cells available out there would be appreciated.

Thanks,

Mik

Hi

I have some trouble with the parental-agents. Anyone seen this before/can give me a clue to get this working?

Tried with my two recursive resolvers first, then localhost. No difference.

From the log

named[3420650]: zone lowinger.se/IN (signed): checkds: empty DS response from 2a00:f680:100:1501::32#53 named[3420650]: zone lowinger.se/IN (signed): checkds: empty DS response from 2a00:f680:10:1501::33#53 named[3428351]: zone lowinger.se/IN (signed): checkds: empty DS response from 127.0.0.1#53

zone "lowinger.se" {

    type primary;
    file "lowinger.se";
    dnssec-policy lowinger-policy;
    inline-signing yes;
    // parental-agents {
    //     2a00:f680:100:1501::32;
    //     2a00:f680:100:1501::33;
    // };
    parental-agents { 127.0.0.1; };
};

dig has no problem resolving the DS record.
