there is an auto-responder detection feature in Yahoo Groups. when an email address sends too many responses to a group in a short amount of time, it is assumed to be an autoresponder. Yahoo disables that email address, the member must then contact Customer Care to get it reinstated.
you need to send yahoo this form
