Hi all, hope your seasonal celebrations went well.
This issue has been a little low on my to-do list but the time has come to get on with it.
Letsencrypt is runnung great on my server, thanks for your stirling efforts. However, I have a couple of clients who use us for ther domain and email etc. whilst their actual website is hosted elsewhere, for example, Shopify.
I would like to impliment a certificate for their email but because the “A” record points to another server not under our control the ACME challenge to our server is not accessed by Letsencrypt and the challenge fails. Not surprising.
I have tried a number of suggestions that I found on the web including putting a TXT record in bind (something like “_acme-challenge.mail.domain.co.uk”) but none of them worked.
So, please can anyone advise what the method is to achieve this.
To avoid any confusion in case my description is not clear, I want to set up a cert for email but not for the website. DNS is running on this server and the slave on a separate server both under our control.
Many thanks for reading.
