You can enter email addresses as well as domains in the Domains/email addresses filter. If you enter an email address, the address has to be an exact match in order to be filtered. If you enter a domain, Policy Patrol will match this with the part after the @ sign of the email address. For instance, if you enter company.com, Policy Patrol will filter all email addresses that end in @company.com.
You can also use the * wildcard at the beginning or end of your entry. For instance, if you enter *company.com, the filter will include all email addresses ending in for instance @email.company.com, @company.com, email@example.com. If you enter company.*, this will include all email addresses ending in for firstname.lastname@example.org and @company.co.uk, but not @sales.company.com. Note that you can only use one wild card per entry.
