How do I white list an email or domain name from my frequent sender

simply go to your cPanel, under MailScanner, click [email Black/whitelist setting], then fill-in email@domain.com for whitelisting an email or fill-in *@domain.com for whitelisting a domain name in the whitelist column and then click on the [change] button, then click [back to the mailscanner configuration] and then click on [change] button once again to retart the mailscanner. You are done. Note: changes will take up to 10 minutes to take effect.
