[IMail Forum] Understanding Kill File

[Barbara ONeal]

We have been being plauged by spam lately for several of our users so I am trying to head a few things off at the pass.   One thing that I haven't used much is the Kill List.  First what I have done is go through the spool and look at several emails that didn't get delivered for one reason or another and 99% of them are spam.  So I took the offending IP address of where they were coming from and did a look up here: http://www.dnsstuff.com to see if they were listed in a spam database someewhere.  If they were listed I have added them to the Kill List.   So my questions are:   1.  Is this an effective way to prevent spam from ending up on our server? 2.  If it is does anyone have a good KILL LIST? - If so would you be willing to share? :-) 3.  If there is a better way I'd like to know it. 4.  We do have Premium Spam but a lot of our users are afraid to just delete this mail.  I do but lots of users don't want to but still want to find a way to eliminate some of this junk.   Thank you for any responses.
