Hello all ... I am getting back into mailing after a few years so I will consider myself a noob. First mail started going out today, of course there were a million mistakes I made, caught and corrected. There is another million that I made and caught and am now trying to figure out. I am mailing GI. I have a reasonable number of Suddenlink emails and I am getting a "421 connection refused" pretty quickly. I can pull Suddenlink out and mail separately but I am not sure how to get through. Do I throttle delivery? Any suggestions would be greatly appreciated. Thanks in advance, Arthur
