MSP Mail Flow
From Configuration > Mail Flow, you can manage how mail is processed before it is delivered to a user. This includes:
Remediation: You can decide whether you want Email Security to automatically assess malicious emails and move them to junk folders or do it manually as the administrator.
Anti-spoof: Email spoofing is the creation of an email with a forged sender address to intentionally mislead a recipient about its origin. This setting is enabled by default, meaning that manipulated display names are checked and an alert banner is added if detected. You also have the option to disable Anti-spoof for your customers.
Frequently Exploited Domains: You can add an alert banner to free email services. Malicious actors frequently launch phishing attacks from these services, so by adding an alert banner, you're reminding users to stay vigilant.
Graymail: Graymail is legitimate marketing email that may be viewed as spam. By enabling this feature, you can treat graymail as malicious, and add a banner to it for all customers. If auto remediation is enabled, graymail is auto remediated.
Anti-spoof
Email spoofing is the creation of an email with a forged sender address to intentionally mislead a recipient about its origin. This technique is often used in phishing campaigns and is an attempt to get a user to click a link and share their credentials or reply with sensitive information.
Anti-spoof is automatically enabled, which means that it checks for manipulated display names and adds an alert banner if detected. Users are then protected against impersonation. You do, however, have the option to disable Anti-spoof for your customers.
To manage your Anti-spoof setting, follow the steps below.
Go to Email Security > Configuration > Mail Flow. Select Anti-spoof from the tab.
Select the toggle to enable or disable Anti-Spoof.
Select Save.
Exploited Domains
Malicious actors frequently launch phishing attacks from free email services. You can add an alert banner to emails from these domains as a reminder to users to stay vigilant, even if the email content does not look suspicious.
To turn on alert banners in emails from these domains, follow these steps:
Go to Email Security > Configuration > Mail Flow. Select Frequently Exploited Domains from the tab.
Select the toggle Add an alert banner to email from frequently exploited domains to turn on alerts.
Select Save.
Graymail
Graymail refers to solicited marketing emails and comes from a legitimate source. Your customers once subscribed to them and now may no longer open or read them. As a result, graymail falls into a category between spam and desired emails.
As an MSP admin, you can enable this feature to treat all graymail as malicious. Once enabled, an alert banner is added to graymail for all your customers. Graymail is always auto remediated.
Go to Email Security > Configuration > Mail Flow. Select Graymail from the tab.
Select the toggle Treat graymail as malicious to turn on alerts.
Select Save.
