Outlook can be at no fault?

Lately, email policy has changed.

So, there’s a lot of email issues lately, especially if it is not properly configured, wrote an article about it last month.

Since there’s have been complains from client lately, about “𝐛𝐢𝐠 𝐢𝐧𝐭𝐞𝐫𝐧𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐜𝐨𝐦𝐩𝐚𝐧𝐲, 𝐰𝐢𝐭𝐡 𝐛𝐢𝐠 𝐈𝐓 𝐭𝐞𝐚𝐦, 𝐮𝐬𝐢𝐧𝐠 𝐌𝐢𝐜𝐫𝐨𝐬𝐨𝐟𝐭 𝐬𝐞𝐫𝐯𝐞𝐫𝐬” is having their email rejected by their small, shared hosting email service under a local web hosting provider.

Usually, when the email you sent have been rejected and with a bounced email error message. It is with an error log or report.

In this case, it is stating that the IP address got blacklisted by a 3rd party antispam listing. It is obvious the sender’s smtp IP is being blacklisted, hence the shared hosting’s antispam is working. Protecting the client.

However, after digging in, using multiple tools, multiple proof, multiple screenshots, and multiple sender score report and mxtools records. Client’s “big international company, with big IT team, with Microsoft server” 𝐂𝐀𝐍𝐍𝐎𝐓 be the 1 having issue.

𝐓𝐡𝐢𝐬 𝐢𝐬 𝐟𝐚𝐥𝐬𝐞.

Anyway, their IT team can’t do anything about it too I guess. Since most likely they are on office365 or outlook.com subs that they can’t really change their IP directly to a clean 1.

Attached Image is 1 of the outlook.com IP sender scores. It is so obvious, and should just ask their services provider to switch their smtp IP, or at least delist from the blacklist.

But instead, they just pass the responsibility to receiver, to 𝐖𝐇𝐈𝐓𝐄𝐋𝐈𝐒𝐓 every IP.

Is like “𝐈 𝐜𝐚𝐧’𝐭 𝐠𝐞𝐭 𝐢𝐧 𝐭𝐡𝐞 𝐨𝐟𝐟𝐢𝐜𝐞 𝐜𝐚𝐮𝐬𝐞 𝐦𝐲 𝐚𝐜𝐜𝐞𝐬𝐬 𝐜𝐚𝐫𝐝 𝐝𝐨𝐞𝐬𝐧’𝐭 𝐰𝐨𝐫𝐤, 𝐲𝐨𝐮 𝐬𝐡𝐨𝐮𝐥𝐝 𝐫𝐞𝐦𝐨𝐯𝐞 𝐭𝐡𝐞 𝐥𝐨𝐜𝐤 𝐨𝐟 𝐭𝐡𝐞 𝐨𝐟𝐟𝐢𝐜𝐞 𝐝𝐨𝐨𝐫.”
