Content Filtering with Enabled Wildcards...

Problem reported by Brian A. - 8/21/2025 at 1:40 PM

Resolved

I updated to the August 19, 2025 edition. The file folder naming issue seems to be fixed.

However...

I have a rule where if there is an attachment with a specific extension, I delete the email.

What I'm finding is that with the "Enable Wildcards" enabled, if the specified extention (e.g., bat) is included anywhere in the filename (e.g., batch.pdf), the condition is considered to be true.

I don't think this is correct.

1) You should only be checking the EXTENSION and not the entire filename.

2) I don't think you should be looking for a substring inside the extension but rather you should be matching the entire extension.

3) I thought the wildcard only applied to * and ? characters. I do not have bat* but only bat

as I mentioned in this thread: https://portal.smartertools.com/community/a97432/new-bug-with-domain-content-filtering-move-message-action-build-9340.aspx#150592

We'll look into this. What happens if you remove the * and just use .bat for the condition? Are you using just "bat" or ".bat"? What about *.bat?

Build 9378 (Sept. 4, 2025) has a fix for this issue.

Fixed: The content filter extension check also evaluates the file name.
