Hi TardisMaximus, 68.230.241.237 is not listed in any of the Cox blacklist tools. Do you use a third-party email client such as Outlook, Thunderbird, or Mac Mail? -Becky, Cox Support Forums Moderator
Hi Becky, this is mail client agnostic. My side is the third party mail gateway receiving e-mail from a Cox e-mail address. One of our spam checks hits against SpamCop and other Tier1 block lists. You can do a look-up directly at SpamCop or Multi-RBL to confirm the SpamCop blacklist (http://multirbl.valli.org/lookup/68.230.241.237.html).
Cisco Talos also reports the IP as having a poor reputation, which will impact delivery to other domains that use IP reputation as a spam prevention strategy. https://www.talosintelligence.com/reputation_center/lookup?search=68.230.241.237
Let me know if I can provide any further information.
