How do I setup a DKIM record with BT

dominicboston27 — Mon, 26 Jun 2023 22:12:23 GMT

Hello,

I'm trying to solve the never ending issues of bounced emails when emailing from btinternet.com with a custom domain to gmail people.

I've setup the SPF as follows on the custom domain as a TXT record. It is the only SPF record.

v=spf1 include:spf.protection.outlook.com include:btinterent.com -all

But I can see in the header of emails send from my dad to me...

Received-Spf: permerror (zohomail.eu: Error in processing SPF Record) client-ip=213.120.69.111; envelope-from=hisEmail@customDomain.org.uk; helo=re-prd-fep-045.btinternet.com;

So I'm not sure my SPF is setup correctly.

Also, do I need to setup a DKIM record/signiture... but do I do this with BT Mail.

Thanks!
Dom Boston

@dominicboston27 if that's a copy and paste of your SPF record, you have a typo in the record.

Try

v=spf1 mx a ip4:213.120.69.0/24 a:btinternet.com ~all

Thanks, will try. Isn't that IP address going to change?

No, it's the address range of the BT email servers.

Works for me using Ionos.

Nice, thank you. I thought the include:btinternet.com should have fixed it tbh.

I thought likewise (I knew nothing about "SPF" first thing this morning but I'm learning a lot 🙂)

However,"liquorice" kindly posted this link elsewhere :-

https://flowmailer.com/en/resource/dissecting-the-spf-record

And that says that the "include" should refer to the domain where your SPF record is specified.

Just adding the details above to my DNS didn't seem to work for me but then I added an "Include" with my domain name (as below) and (so far !) I think it has worked.

v=spf1 mx a ip4:213.120.69.0/24 a:btinternet.com include:<my domain name>.com ~all

Many thanks to "liquorice" 🙂

You can test it by emailing and checking the message headers 😊

@licquorice this is still failing

Received-Spf: permerror (zohomail.eu: Error in processing SPF Record) client-ip=213.120.69.122; envelope-from=andy@domain.org.uk; helo=re-prd-fep-046.btinternet.com;

I will try @jeremygoodall approach

@jeremygoodall

Thank you, this was the solution that worked. I think that the important bit was the last bit, as I had the other parts in before it worked. include:<my domain name>.com

v=spf1 mx a ip4:213.120.69.0/24 a:btinternet.com include:<my domain name>.com ~all

I'm looking to setup a DKIM as a BT customer

That's because BT customers are using the BT servers/domain and they do not need to make any changes to anything as it is all correctly set up for them.

Even although you are a BT customer your are using your own domain so it must comply with BT.

Nice one

v=spf1 mx a ip4:213.120.69.0/24 a:btinternet.com include:<my domain name>.com ~all

Works a treat👍

is it possible that the bt server range has increased as I just got a spf fail return because :

5.7.26 not pass with ip: [213.120.69.111].

Hmm, that address is covered by the /24
