Thanks to several of this group's suggestions I am off most blacklists, a hellish trip at best.
But I still keep going back and forth with the "SORBS" lists. Mxtoolbox's test say I don't relay. But SORBS says I am. Off their list for awhile and then back on. Are there deeper tests I need to run? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
