A bit of a long shot, but does anyone have a contact at qq.com / Tencent Mail?
We moved outbound IP address a few months ago, and the only provider that we are still needing to deliver to using the old IP addresses is qq.com, which is rate-limiting the new range with the messages: "550 Ip frequency limited" and "550 Sender frequency limited" Thanks, Andy _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
