I have a question regarding adding CNAME records to my DNS records on Cloudflare, I have added a “second” email sending service to my customes, the provider has asked that I add 3 additional CNAMES to the DNS records in order to verify delievery. Is there any issues with adding additional CNAMES to the records , a the moment i only have 2 CNAME records for my hosted site, just dont want anything to break. Thanks
DKIM records have the following format:
The selector is used to identify which key was used to sign a message. So long as two providers do not decide to use the same selector names, there is no clash. The number of different selectors does not matter at all.
I use several mail sending solutions, and have yet to come across a clash.
