Re: Open Relay / Zombie Computer

Access Control?

You are correct here- this will let anyone generate mail
that is logged onto the server.
-However-
The only anonymous way someone can be logged onto the server
is if they are viewing one of the hosted websites

->Access >Relay Restrictions >Only the list below (empty) &
Allow all authenticated to relay, regardless
******
The empty list for allow will not allow any relaying unless
they are authenticated users.

Since I did this I have no issues with relaying, but I have
logged plenty of rejections from the former abusers- even
someone who has a computer name identical to my servers IP
address
