In order to leverage missed malware alerts you must have an administrator email address configured under Alert Settings. Upon logging onto Client Net portal the admin address must be entered here:
Services-> Email Services->Anti-Malware->Alert Settings
You can also enter a custom sender address or the default address will be used.
The notification email received will contain the following details:
Subject: Warning: An infected email was delivered to recipients
An email message was delivered to end users and was later determined to be infected by malware. Please take appropriate action.
Date sent: %d
Envelope senders: %e
Envelope recipients: %r
Subject: %t
Source Sending server IP address: %S
Mail server name: %m
Message ID: %i
Suspect attachment filenames: %y
This configuration settings can be applied at a global or domain level. Please note at this time the text for notification email is not customizable unless you have ATP Email.Cloud service.
