262308 Fix to Email Delivery Script

I need someone that knows how to hit Yahoo inboxes (legitimately) I have an autoresponder script I like to use that is self hosted, I have my opt-ins that I import in, but apparently yahoo is blocking attempts to mail, and everything is going direct to the spam folder. We're talking 'test' messages even with no flag words used. :( Please bid only if you know how to resolve this issue. Thanks .
