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.
