Hi all. We're seriously scratching our heads as to why Yahoo! in particular but also Hotmail are blocking or filtering our legitimate emails. I'm using the spam analyzer in Litmus and our emails are passing through Barracuda and Postini but are not getting through Yahoo!. I've run a free, online HTML assessment on several emails that are potentially being blocked and the code has minor issues. Has anyone experienced the same thing? Any resolutions?

Thanks! Dan
