DKIM public key

Hi
I recently discovered that my outgoing email was not getting through to some recipients.
Other posts on this forum led me to set up DMARC and SPF in the DNS settings for my NAMESCO email forwarding service..This has recified the issue. 🙂
However I now get DMARC reports showing DKIM "fail" for some recipients
I understand that to set up DKIM in my DNS settings a public key is required to validate outgoing mail encryption. Does VirginMedia provide this info?

The short answer is no, you need to do that through Namesco via  your Online Control Panel.

They have a step by step guide on how to enable DKIM for your domain here: https://www.names.co.uk/support/articles 

If you need any further clarification or details your best bet is to contact Namesco.

Re: DKIM public key

Many thanks coenoby for paying attention 🙂
Not sure if I'm between a rock and a hard place here.
In order to have Namesco provide the DKIM setup I have to purchase and use their Authenticatred SMTP service. At present I am just using email and web forwarding from them. Nevertheless SPF and DMARC are successful updates to my domain DNS settings at Namesco.
I am using (and paying loads of money for) VirginMedia's SMTP server so are you sayng it's not posible for them to provide DKIM authentication for my outgoing mail?

DKIM uses the domain in the email "From:" address in the email not the SMTP server so your DKIM keys are not really anything to do with VM. Even though you  may be sending your emails through VM's SMTP server they cannot provide you with the key to use in your DKIM record.

The thing is that if you are sending personal domain emails they should ideally be sent via Namesco's server.  As far as I'm aware, Namesco servers are smtp.hosts.co.uk and imap.hosts.co.uk.

However, I see that you have set up an spf record for your domain, so have you set that to specify that your emails are coming from  Virgin Media's email servers. I assume you did, but if not the record in your DNS should be:

v=spf1 include:_smtprelay.virginmedia.com ~all

 If you have the spf record for your personal domain set to specify Namesco's servers that will definitely be causing you problems. Setting it to specify that your emails will be coming from the VM servers is certainly not ideal but if you have not done that already you could try and see if you get fewer errors.

I am using (and paying loads of money for) VirginMedia's SMTP server

The thing is that VM only provide that SMTP server so you can manage your VM email accounts (so @virginmedia.com / @ntlworld.com / @blueyonder.co.uk addresses).  Using your ISP's servers to send personal domain emails used to be ok in the old days ( that's what I used to do with my emails in the early 2000's) but it's definitely not recommended now. Having said that VM do not actively block you from doing it.

As far as VM are concerned their email service has only ever been just an added value service included in their broadband package and is provided at no additional cost.

Like may VM broadband customers I never have used VM's email service (or the "free" email service of any other ISP come to that)  and  of course many VM broadband customers only ever use the VM webmail service and so make no use of VM's IMAP / POP3 and SMTP servers.

By the way, since May 2022 VM no longer provide email accounts to new broadband customers and existing customers such as yourself can no longer create new additional secondary VM addresses. Clearly, like most of the other ISP's, the provision of an email service is not high on their business priorities going forward,

Re: DKIM public key

Once again many thanks, and for clarifying the situation.
I'll carry on as I am for the moment. If the lack of DKIM becomes a problem for me then I can always pay up to use the Namesco SMTP server 🙂
