I have since solved this problem by moving my forwarded business mail to Gmail.
click the checks of ur messages and click on move and move them into ur inbox or into a special folder u may wanna create for work documents
You’ve already added the business address to your address book—that’s essential.
Now go to Spam folder and open each of those mails and, then click the “not spam” tab, and they will be returned to your inbox, and should go there from now on.
Go to “Options” It is above your email
Click on “Mail Options”
Click on “Blocked Addresses”
Click on the Address you want to remove block
Click on “Remove Block”
This should remove the block and allow it to start coming into your inbox.
Hope this helps!!!
