Snowbat Posted June 2, 2021 Share Posted June 2, 2021 13.64.0.0 - 13.107.255.255 is Microsoft but SpamCop reports 13.68.154.53 directly to the spammer. I've seen similar misreporting for other Microsoft-hosted spammers. https://www.spamcop.net/sc?id=z6713311620zae746f26cf2e5fb58c2b5b7dfb392cb3z Tracking message source: 13.68.154.53: Routing details for 13.68.154.53[refresh/show] Cached whois for 13.68.154.53 : abuse@microsoft.com Using best contacts abuse@microsoft.com Using rdns to route to correct Microsoft department host 13.68.154.53 = envio.dabitoconta04.com.

Snowbat Posted June 7, 2021 Author Share Posted June 7, 2021 Even at reporting time, the cached address was abuse@microsoft.com. The problem is whatever SpamCop is trying to do at the "Using rdns to route to correct Microsoft department" stage. Quote Link to comment Share on other sites More sharing options...
