What attachments are blocked by DataYard’s Email filtering?

A complete list of attachment types that are not allowed through DataYard’s email services.

You should never accept or download any type of file from an unknown source. To help stop the recent increase in malicious files being received via DataYard email accounts, we have implemented new policies regarding the sending and receiving of certain executable files.

If someone attempts to send an email with one of these attachment types, they will receive a non-deliverable message letting them know that we do not accept these types of attachments for security reasons. The message will not be delivered to you.
