i've stripped html, images, etc, it's just text

i'm running php through suphp(i think?) so that emails are not sent from "nobody"

i've set up an spf record

i've had servint(where site is hosted) properly set up the A records(though i can't be totally positive that they know what they were doing)

the only thing i haven't done(that i know of) is gone through the domainkey process through yahoo

thanks again for any help!
