Regarding retrieving of encrypted documents traversing through MTA

[SANDEEP_DEGAONK]

We intend to block all encrypted attachment by Check Point Threat Extraction blade and send notifications to end-users about the same. Before enabling this, we need to confirm whether we will be able to retrieve & forward that encrypted attachment to the intended recipient upon receiving such requests from end-users.

This is not possible using the TX blade as TX can only be used with several file types that can be rendered into a non-malware visual representation - encrypted documents would have to be unencrypted first and then has to be of a supported file type for TX.
