I use GoDaddy for my company hosting. Our Office 365 email gets sent out by a Azure cloud (ip addresses are registed in Austria). One set of servers starting with 40.*.*.* are fine and only have a few black listings
The other set of servers 52.101.132.* have a very high proportion of IP black listing.
e.g. 220.127.116.11, 27,78,76,68,13,18,76,42,75,29,33,10,23,30,62,20
This is not a complete list.
The result is that our emails randomly go to spam files - we have suffered late payment of invoices due to this.
I have checked our emails through mail-tester and they get 100% score when they go through the 40.*.*.* servers
I have used glock apps spam tester to identify these ip addresses
A sample report for spam is here
The same email sent on the same day was also reported like this - not spam:
These are not my servers and the service at https://sender.office.com/ is hard to use for multiple IP addresses and the captur is horrendous
Please can you monitor your IP addresses and ask for the blacklisted ones to be delisted?
