It seems my last thread led to one forum bug and it can't be displayed completely. So i format my questions in this thread. Recently my SA score rose a lot for two hitting two rules. BAYES_99 and RDNS_NONE (rDNS is set) i've searched a lot on this forum and other places, still didn't find any effective solution. Can anyone offer some solutions? I also have one question for junk words. I always mix text and image creatives. But for the image creative, I always get STYLE_GIBBERISH. I know it is because of style tag. So now my temporary solution is add some #fff words at the end of the mail to bypass SA rule. Is this a good solution? Thanks very much!
