Hello All. I'm new to using Mimecast. I'm trying to assist one of my users. My user blocked an e-mail address, numerous times, using the Mimecast Outlook plug-in (Outlook 2016/Office 365), but he is still receiving e-mails from the blocked address. I checked the administration console and I see that the sender address is set to Manual, blocked, untrusted. I checked previously received emails from the address over the last week to see if the sender address might be changing slightly, as a way to explain why the e-mails were still getting through, but they all look the same. I selected the address and clicked Block again, but I'm concerned this will not work. Does anyone have any suggestions on how I can figure out why the supposedly blocked e-mail address is still able to send mail to my user? Thank you.
Please note, in the second attached picture, from the second row down, the "To Address" shows the recipients full first and last name, not an e-mail address like it does in the first row. This is the same for the sender detail as well. I'm wondering if this might have some impact on why these e-mails are still being delivered to the user.
Answer:
Have a look at your "Permitted Senders" policy and make sure the sending address is not listed there. Navigate to the below to have a look:
1. Navigate to Administration --> Directories --> Profile Groups
2. Click on Permitted senders
3. Do a search for the sending address. If it is here you can remove it from here.
What you could also do is add the sender to the "Blocked Senders" group found in the "Profile Groups" if you like.
