Issue:
- How to block specific extensions using “Disallowed Inbound Files“ for incoming, outgoing and Internal with F-Secure Email and server security.
- I want to block only these extensions " *.doc *.docx *.docm *.xlx *.xlsx *.xlsm" for Internal email only, but not Outgoing or Incoming
Resolution:
Each mail route has its own settings. You need to individually define which match list to use.
You can use Policy Manager Console to make these changes, if you are managing your F-Secure Email and Server Security via Policy Manager, or use the Web Console to login to your Email and Server Security locally.
As you can see here, I am using a different Match list for each of my mail route, where I have defined the file types I want to block.
On Actions, I have however selected "only drop the attachment", not the whole message.
Now, I have activated each list for my Email traffic scanning accordingly, and each of them has their own list that contains the Extensions I want to be blocked from attachments.
Note: I did not use the default "Disallowed Files" from Lists and templates as I wanted to have my own customized lists.
If you are using the default list on each email route, it means that the same rules will apply for all.
