How to white/black list either a user or domain
Although Xeams allows white/black listing users as well as domains, we strongly recommend you read the following section before making any changes to the rules.
- White listing a single user is safe - Use the sender's entire email address when specifying the rule
- Black listing a user is NOT recommended - This is because email addresses can be easily forged. The only reason to black list a user is when you are confident the sender is not forged.
- White listing a domain name is generally safe - As long as the domain names do not belong to well known companies, such as Hotmail.com, Gmail.com, BankOfAmerica.com, CitiBank.com, AOL.com, etc., it is okay to white list a domain.
- Black listing a domain is NOT recommended - This is because domain names can be easily forged.
Instead of white listing a domain, consider adding them as trusted domain.
Steps to White/Black list a user or domain
- Log in to Admin Console as admin
- Click Content Filters under Filter Management
- Click Sender Filters
- Add a new Sender Filter
- Enter an email or domain name in the Search String. For example: user@somecompany.com or @somecompany.com
- Enter a negative value to white list and a positive value to black list. Do not enter a very high number. A score around (+/-) 100 should be sufficient to drag an email in either direction
- Leave other values as-is
- Save the rule
