Not my own, but an associate has his TWC IP address listed as can be seen here:
The cause has been traced to a Chinese IP of: 188.8.131.52
The result is that outbound emails sent through a third-party SMTP server are blocked as spam by some, not all, email recipiant's servers. This began suddenly after years of proper function. At this point, I cannot tell whether spam was generated spoofing his domain and IP, or if it actually was routed through his third-party SMTP server. His domain provider claims there are no issues associated with his account.
Does anyone have any idea as to the proper and expediant method for resolving this?
