Autoresponder for free  

I sent a few to many messages to one of my groups, and Yahoo put me on autoresponder. Can someone give me a link to the Yahoo help site so I can get myself off of it? I can’t find it anywhere.

I use Incredimail and this morning all my Yahoo groups emails came back saying unable to deliver because I had turned on the “autoresponder”. I did NOT turn it on! When I go look at my pref page it says it is ON but when I go to the page that says “vacation response” it says it is OFF. What is going on here? Who turned it on and why can’t I turn it off? It tells me it’s off already
BTW..I was also mysteriously unsubbed from the Yahoo group I was posting too at the same time. Someone told me that it was because I posted to many times and Yahoo thinks I am a spammer?
help please
Thanks
