I am still new to configuring servers (mail servers included) and have some
question regarding Anti Spam settings and what to put in the router.

I actived the AntiSpam settings:

€Relay for Clients Only
€Use Blacklist DNS Servers (entered "" and
"". I do not use "" as we
have some clients who provider is on the dialups list)
€Verify Return Paths

Then in the router I have the entry:
<*%@blacklisted>  =  blacklist
<*@blacklisted>  =  blacklist

But what is NULL@NULL and what exactly is the function of this entry? And
why is this horrible as stated in a previous posting...
