Mail bounced back

Please read this. It may help. SPF is being used quite a bit. I know I use it at work on our system.

Thanks. I had already read something similar, which is why I tried sending mail from within Earthlink's web mail system, and that worked. I think it's irresponsible of the people at Furious Apps to use an e-mail address that filters out a bunch of incoming mail. In my case, mail sent from both an Earthlink address and an address from one of my domains bounced. So how many unsuspecting, clueless end-users have theirs bounce back, too--and have NO IDEA why?
