    Hi guys... The past week, I have noticed soft bounces coming back from AOL and dont know why? To be more precise, aol keeps returning this : failed,5.0.0 (undefined status),smtp;521 5.2.1 : AOL will not accept delivery of this message..
    I would greatly appreciate any help... Thanks

    What is your outgoing IP address?

    Have you checked your Sender Score and MX Toolbox reports?
