Since I signed up I don't get any emails from people with Yahoo mail (and they get bounceback emails saying it was undeliverable a day later), yet I get email from those with AOL mail. I have received emails from a friend with his own email server containing his business name but have not received from others.
I don't understand the selective incoming mail. It's frustrating and if this is an indication of the mail service we will definitely not upgrade and pay for the next tier of email service.
