But I have to know in any case of all the domains that send out legit messages trough our server.
No, you do not. You can simply add the "v=spf1 +mx ?all" to all your domains.
However, if you want to take the time to find ones that only send through your server, you can change them from "v=spf1 +mx ?all" to "v=spf1 +mx -all".
If not: Would it be possible to have something like
LOGSPFINFO ON
that can be enabled temporary for some days to write one line for every outgoing message. (eventually also in a separate logfile)
With the current interim release, a C:\spf.log will be recorded for domains with SPF entries, and C:\spf.none for domains without SPF entries.
