Fetchmail - How to stop it at booting

I've been using Mutt for a while.
Now I would like to avoid the sutation when Fetchmail is started at booting or logging without my decision.
But I can not find any script that currently starts my fetchmail.

How can I find it, where????

Thanks in advance.

You can just use "chkconfig" to turn off fetchmail for all run levels and then it'll never start.
