How do I setup a DKIM record with BT

Go to solution

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 😊

@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
