Question Incorrect SPF record referencing older subdomain

[brownbag]

I've just moved created a second domain on my plesk server and in the new domain, I'm managing DNS settings in plesk

One DNS entry is as follows:

HOST=domain
TYPE=TXT
VALUE= v=spf1 +a +mx +a:sub.olddomain -all

My inclination is to remove the reference to the older subdomain, as that whole domain will be removed anyway and I don't need to send mail from that domain.

Do I need to include references to my new subdomains with a parameter such as: +a:sub.domain, or does the inclusion of the of +a and +mx in the value, mean that any subdomains are already approved?

If both domains use the same mail server (i.e your Plesk server) just a v=spf1 +a +mx -all in the SPF record will suffice.

Thanks for confirming.
