In the context of emails, a whitelist is a list of email addresses and domains that are regarded as safe. Emails received from this list are exempt from spam filtering rules. This list is also called the Trusted Senders list.

A whitelist is like a VIP list; it is a list of items that have explicit access to a resource and/or granted special privileges.  The opposite of a whitelist is a  blacklist which is a list of items that are denied access to a resource.

For example, your main domain is companyname.com; you also have the domain companyname.com.ng which you want to point to your main domain. You would achieve this by setting up a CNAME record. Thus, anytime a website visitor types in companyname.com.ng, they will see the same content displayed on compnayname.com.

NB: A CNAME record always points to another domain/subdomain and not an IP address.

When a mail server receives email from an unrecognized sender it temporarily rejects it and informs the sending mail server to resend the email. A legitimate mail server will resend the email after a short delay; the email would then be accepted by the receiving mail server and subjected to further spam checks. The receiving mail server adds the sender to its whitelist for a specified period of time (i.e. 1 month). Subsequent emails from the sender won’t undergo greylisting during this period.

Greylisting works in reducing the amount of spam received because a lot spammers won’t bother to resend the rejected email.
