A few comments here:
1) The "minimal" SPF record is common and sufficient in most cases"
TXT "v=spf1 mx -all"
What I mean by common and sufficient is that it works perfectly in
the cases where:
- There only valid sources of mail for your domain are your mail
servers (the ones listed in your MX records)
- There are no web-sites, database servers, or other sources of
mail that will appear to come from your domain, but will come from
another server
- You are not using a relay, SPAM filter, Smart Host, or other
3rd party that touches or manages your mail
2) If you are hosting for more than 1 domain, consider creating an
"importable" SPF record:
_spf.domain.test IN TXT "v=spf1 -ip4:<address> ?all"
This will allow you to use the same SPF record in all of your
hosted domains that looks like:
other-domain.test IN TXT "v=spf1
-include:_spf.domain.test -all"
NOTE: The ?all at the end of the includable record says to
essentially pass on any error number to the next level, then the -all at
the end of the "real" (or, outer) SPF record says that this is for real.
Many samples you'll seen online will end the record with "~all"
instead of "-all" -- the "~all" means you're testing and SPF isn't "for
real" for your domain.
By using the include, you can change your email host's address
or MX records or you can add a 3rd party SPAM filter or whatever, and
when you change the _spf record, you'll be changing the value for all of
your supported domains.
I hope this helps

You only want a txt record. Spf records are deprecated.

Aslo ,
from the wiki ( Thanks Eric )
should we have both entries:
By far, the most common entries for an SPF definition will be:
domain.tld. IN TXT "v=spf1 a mx -all"
domain.tld. IN SPF "v=spf1 a mx -all
Cheers

What test to confirm the SPF records ?
Also does anyone have a link to set domainkeys?
Cheers.

Dave,
I use this:
v=spf1 mx a ip4:<your server's ip> -all
