My sister and I both use Microsoft Outlook Express version 6 (on seperate computers). We have never had problems with email before but all of a sudden she's not getting messages from me. She verified (Tools , Message Rules, Blocked Senders list) that she does not have me blocked. If I reply to one of her messages, she gets it. If I send her a message from an alternate yahoo mail account, she gets it. If I send using my roadrunner account, she doesn't get it beut everyone else does. I deleted her username from my contacted list and let it automatically add itself beck when she sent me a new message but when I send she still isn't getting them. Anyone have any ideas on what to do or where to look so that my messages to her go through? As always, I greatly appreciate all your responses!
