I have the Cox Communications HiSpeed Internet package. It works great, however, email being sent to/from one of my domains started to bounce. After a little digging it seems that the smtp.west.cox.net SMTP server is blacklisted by sorbs!
Cox forces all residential customers to use their SMTP servers to help prevent spamming..but it seems they got hit themselves. Anyone else have this issue? If you’re a Cox rep, a response would be appreciated. It seems calling tech support has been less than useful.
