Hi All, I'm trying to warm up some new email server IP addresses, and I'm getting the following error sending to Microsoft addresses:
[redacted].mail.protection.outlook.com 550 5.7.511 Access denied, banned sender[45.79.227.220]. To request removal from this list please forward this message to [email protected]. For more information please go to http://go.microsoft.com/fwlink/?LinkId=526653. AS(1410) [ DM6NAM10FT110.eop-nam10.prod.protection.outlook.com 2023-03-04T01:00:34.878Z 08DB177D8CA1B04E] I had gone through the delisting process at https://sender.office.com as instructed, but I never heard back. It'd be difficult for me to forward these messages to [email protected], is there another way to get these new IP addresses unblocked? For reference, the list of IPs I'm trying to warm up are: 45.79.227.220 45.79.224.9 192.53.124.123 45.79.224.7 192.53.124.254 173.255.243.56 Thanks, Mark
