Hi there. Trying to setup whitelisting, but our IT department is concerned with the degree we are opening up our servers to. See note below.
Are you able to provide the specific mail server addresses as requested by IT below?
*Sending domain: e2ma.net
*IP Range: 18.104.22.168/24 (22.214.171.124 to 126.96.36.199)
*IP Range: 188.8.131.52/27
*IP Range: 184.108.40.206/25
*IP Range: 220.127.116.11/26
"I can whitelist the Emma servers in our spam system, I can’t however whitelist this for Junk/Clutter in outlook. I can’t add those IP ranges below as the subnets mask is a /24 and that is way too many IP Address to whitelist. I highly doubt this company has 254 e-mail servers that send e-mail in that one range. Whitelisting IP Addresses opens the system up for spammers to spoof IP Addresses and that allows spam/viruses to get into the system bypassing all scanning and protection rules. I need the specific mail server addresses. If they can’t supply those then I can whitelist by domain and see how that works out."
Please help, as we've had a number of issues with the receipt of test emails internally,
