No, the problem is you do not know how to use postfix, and have allowed
this. By *default*, postfix will not allow relaying. Unfortunately, you
have changed things in the main.cf file to allow anyone within your ISP to
relay through you. I am on the road, traveling, but I can tell you that
you have screwed up. Taken from your previous email in your main.cf file.

This means that anyone within your ISP class range will be allowed to
relay through you. If you actually *read* the main.cf file, it will tell
you so. It is right there in black and white in the mynetworks section.
The default, from memory, is mynetworks_style = subnet and that makes a
lot of difference. Your IP address will probably be in several RBLs,
making it hard for you to send mail in the immediate future. Funny part
is, I don't even use postfix.
