Trusted senders

MetaDefender Email Gateway Security supports a global trusted senders list. This list can be used to bypass Anti-Spam and Anti-Phishing checks for emails sent from specific IP addresses/ranges and/or senders.

Overview

The Trusted Senders is available by navigating to Settings > Trusted senders.

Adding trusted sender entries

IP address

To trust a specific IP address, click on the 'Add sender IP address to filter' option and specify the IP (v4 or v6) address and click 'Save' to store the changes. Any emails from that specific address will bypass any anti-spam/anti-phishing checks in MetaDefender Email Gateway Security.

IP range

To block CIDR IP address range, click on the 'Add sender IP address to filter' option and specify the range, for example: 192.168.129.23/17 and click 'Save' to store the changes.

Sender email address

Trusting a specific sender (SMTP MAIL FROM) is done by clicking on 'Add sender domain or address filter' and specifying the address to be trusted. Please note that a Regular Expression can also be used to trust multiple addresses with a single filter entry. If a regular expression is used as value, make sure to change the drop-down value to 'Regex'

Sender email domain

To trust emails from a specific sender domain (SMTP MAIL FROM), simply specify the email domain to be trusted. If using a Regular Expression to define a domain filter, make sure to select 'Regex' in the drop-down to the right of the value entered.
