No incoming messages

We have stopped receiving any incoming messages in SupportCenter Plus. When testing the mail server settings, we get the error message "Email settings saved successfully. But error occurred while trying to check connection with mail server. Problem connecting to mailbox." We're using Version 7.6.0, Build 7607 on POP3, and as far as we know, no server or other settings were changed before the problem occurred. Thank you for any help you can offer.
