Thanks Marc, but is there any problem associated with zoneedit not
running SPF code at their end, since they not only act as my DNS but
also as my secondary MX?
Some spammers will send to your secondary MX without even trying your
primary MX. So if you leave them set up as secondary you may still get
stuff that slips through via that route. But, I think you have some time
before this will start to make a difference. We are encouraging people to
start using SPF right away, but there are still going to be a LOT of
domains that have no SPF info, even a year from now or more, at least that
is my guess.
Your domain will still be protected from forgery as long as you publish the
TXT record. (There is no SPF type of DNS record yet but we hope there will
be in time - for now just publish in TXT form). This is subject to the
same disclaimer, few mail receivers will check SPF at first, though it only
takes a few large domains like Hotmail, Yahoo, etc in order for spammers to
change their behavior.
Anyway, the point is, you can use one or both methods at your choice, they
are independent from each other.
