How we’re protecting you from suspicious emails

We’re introducing a new tool for keeping you safe from suspicious emails. Soon, we’ll be enabling ‘digest notifications’ from our email gateway, Mimecast.

A ‘digest notification’ is a message informing you that you’ve received a suspicious email that’s being held by Mimecast. Mimecast holds emails that have a high spam score, contain a suspicious message structure or unsafe attachments – preventing you from accidentally opening it, if it was received directly.

When you receive a ‘digest notification’ you are given three options on what to do with the email/s that have been held:

Release: allow the email to be sent to you - you know for certain it’s not suspicious.

Permit: allow the email to be sent to you and always allow future emails from this sender to be sent to you - for emails from a known sender which has been held by Mimecast in error.

Block: you don’t know the sender and believe the email to be suspicious - the sender will be blocked.

The image on the right is an example of what a ‘digest notification’ looks like.

What a 'digest notification' looks like

‘Digest notifications’ are sent once per hour, so if you receive several suspicious emails within a one hour time period, you will only receive one ‘digest notification’ which will list all the emails being held.
