I have multiple mail servers for my domain and I have all of ther ip addresses covered in the spf record with:
ip4:xx.xx.xx.xx/24
I have reverse pointer names for each email server created in my dns server and a records in my dns server for each mail server and each email server has it's own name such as:
mail1.mydomain.com
mail2.mydomain.com
etc - I have 24 in all.
My question is this:
do I need an 'a' entry for each of my 24 mail servers in the spf record such as:
a:mail1.mydomain.com a:mail2.mydomain.com a:mail2.mydomain.com
or can I wildcard all of the names since they're all in mydomain.com with something like a:mail*.mydomain.com
or do I even need 'a' entries at all since their ip addresses are covered by my /24 entry?
???
thanks in advance.
Jeff
