My sbcglobal.net emails have disappeared...

All but one of the emails in my sbcglobal.net email account Inbox have disappeared in the last 24-36 hours. Not moved to Trash, not moved to Junk, not moved to Archive, just gone. This, coupled with the insatiable email flood, and the inability of Yahoo Mail, (separate account), to correctly filter emails, (it moves almost everything to Junk), makes me think sbcglobal.net and Yahoo Mail have become worth exactly what we pay to use them. I'm using Apple Mail, and set up rules to filter the spam by using factors such as Norton, whitespaces, subscription, etc..., have marked them as spam in the Mail app, but they just keep coming.

I need my emails back! And the Spam filters fixed!
