If you find that some incoming emails are going to spam from legitimate email addresses, you can white-list their domain so they are delivered to your inbox.
PLEASE NOTE: This is only recommended to be done for business domains only and NOT free domains like: gmail, hotmail or outlook etc. unless you use the FULL email address.
Login to your cPanel hosting account via here.
Go to Email/Mailscanner
Access white/blacklist
add domain like: *@clientdomain.com.au
and your done. The same can be done for BLACKLISTING also but be careful here as well.
