Click Local Good Sender Domains and add the domains you want to white list inside
In some cases, it may be safer to whitelist by IP rather than by domain. Email addresses are frequently spoofed so unless you are using technology to check this, you may start receiving spam appearing to be from the whitelisted domain.
I feel that there is no actual safer whitelist be it by IP or domain. Some companies do use shared hosting services thus sharing IP addresses with possible spammers, whitelisting that IP might allow a flood of spam though I could be wrong. Others could have dedicated IPs but allowed relay for certain external domains which may not be spam free.
In my environment, I have both IP and domain whitelisting: IP whitelisting for group companies and domain whitelisting for others.
Even so, there are incidents of spam from group company IPs which have been whitelisted so I've been reviewing my whitelists frequently and disabling whitelists for IP or domains which have incidents of spamming.
This document describes the steps that enzo81 mentioned above and also highlights the point that Amanda raised about the dangers associated with whitelisting a domain due to spoofing.
