Which option defines a method that can be used for matching senders and recipients for the "example.com" domain?

The method that can be used for matching senders and recipients for the "example.com" domain is typically defined by using a wildcard character (*) in the email address.

Here's how it works:

1. In the context of email systems, a wildcard character (*) can be used to represent any string of characters.

2. So, to match senders and recipients for the "example.com" domain, you can use the wildcard character in the email address like this: *@example.com.

3. This means that any email address that ends with "@example.com" will be matched. For example, it will match "[email protected]", "[email protected]", "[email protected]", and so on.

4. This method is commonly used in email systems to apply rules or policies to all users within a specific domain.

So, the option that defines a method for matching senders and recipients for the "example.com" domain is using a wildcard character (*) in the email address.
