Hello again,
I thought the previous issue was resolved but my clients emails still seem to be blocked by AT&T. AT&T is of absolutely no help. I've sent in requests to be removed from the blacklist, I have a reverse DNS (PTR record setup already). My clients are fed up. They think I'm not doing something on the server end. Is there anything anyone could shed some light on for me? Thank you in advance.
