Posted by Mark Murray, Last modified by David Szoke on 25 April 2018 09:54 PM

To quarantine certain types of attachments that have been encrypted you can use the following filter criteria:

Company Settings>Filters

Create an Inbound filter with the following logic:

If Attachment Name IS *.zip

AND Attachment Type IS Undecipherable Attachments

Then Quarantine

You can put as many attachment names as you want e.g. *.doc, *.docx, *.xls.
