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

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
From https://multirbl.valli.org/:
45.79.227.220 - 5 blacklists
45.79.224.9 - 3 blacklists
192.53.124.123 - 2 blacklists
45.79.224.7 - 3 blacklists
192.53.124.254 - 2 blacklists
173.255.243.56 - 3 blacklists
All those IPs are reported by UCEPROTECT and Polspam at the moment, and
I have seen that the 800lb gorillas seem to refer to UCEPROTECT, or at
least their findings coincide.
There are no 'new' IP addresses any more, and in terms of providers,
Linode are going to reuse IPs a lot.
