Hi,

You can create a message/content filter to block files with attachment name == "(?i)\\.ppsx$".

(?i) makes the search term case insensitive.

$ indicates ends with in regular expressions.

\ is used to ensure the character "." is treated literally.

Thank You!

Hello Libin,

Thank for the information. We would like to know if this is correct (please see attached)? 

Hey John,

Add a single "\" before the period, the device doubles it automatically in content filters.

Message filters require us to add two "\".

Also, I would recommend the quarantine action for testing to see the filter works as expected before you drop emails.

Hello Libin,

We have successfully block the ppsx but in our message tracking the mail server is still responding even if the .ppsx is block by our content filter.

Message ID ending with 5757 was dropped by the content filter, I see the DCID or delivery connection was for message ID ending with 5835.

You would need to review the message tracking details to confirm what that message ID was for.
