select all of your whitelist_from entries, parse out the domain part,
dig the TXT record for each domain, then display only the ones that have
a v=spf1 notation. That would give you a list of all of the domains in
your whitelist_from that could be migrated to whitelist_from_spf
... provided, as Matus pointed out, all your whitelist_from entries are
nicely formatted one address per line, and provided you don't have any
domain wildcards. If those two conditions aren't met then you'll have to
do some extra mangling to extract the domains properly. It also only
looks for TXT RRs, so if any of the target domains are using only SPF
RRs it won't find them.
