Greetings

i have an internal dns server it resolvs all my queries from the inside.
I have a mail system requesting an spf record.  Should i add the same record on the inside as i do for the outside ? i don't want internal address space to mess with external.

i would say just place it on my external dns. But it's an internal content filter that is asking for the record, so then shouldn't place it on the inside?

any insight suggestions and flames welcome
