Groupwise rules to fight spam?

I tried to setup rules in groupwise so it will automatically move those junk mails to my junk mail folder. Some companies use randomly generated sender e-mail address to send the same advertisement to me every day, so it doesn't work by using the senders' e-mail address as a criterion to block the advertisements. I used unique keyword found in the message of advertisement as criteria to block them but the messages with the same keywords still go through and not get filtered. Would you help me out? Thank you.
 
You ought to put in a 3rd party anti-spam/anti-virus solution. Yeah you could try to continue messing with rules, but you'll find that it's a never ending battle.

Some options I have dealt with are:

GWGuardian by Messaging Architects (sits on another server and mail passes through it - highly configurable to do various levels of spam detection). Powerful solution but currently requires a separate Windows server to run on. A Linux version will be available by March.

GWAVA by Gwava (Runs on top of NetWare server integrating into MTA). Some people prefer this, I don't care for it. But it is pretty easy to configure and manage.

Astaro - perimiter solution that provides firewall, intrusion detection, etc... but also has a decent spam filter component. Not as powerful for anti-spam as GWGuardian, but for an all-in-one security solution it's pretty good. It comes in appliance form or you can install it on your own hardware. Very easy to configure and use.

Security Manager by Novell - basically same as Astaro but OEM'd and packaged by Novell. Note that it is one version behind the full Astaro product.

Another thing that would help is just having GroupWise 6.5 or GroupWise 7.0. They have a few more features not available in GW6.0 like RBL's. Just setting up RBLs can cut your spam down by 75% (rough guess)

The GWAVA people have a product they resell called GWAVIX and it works pretty well for us.

It is a simple linux box that checks itself for hacks and automatically updates signatures every 10 minutes. It has an easy web interface to administer. Users get a daily report of blocked mail so they can release things themselves.

Some of the old hands here were getting 80-100 spams daily, now they get 1 or 2 at most.
 
We use GWAVA's Guinevere for spam and it works very well.

Our email addresses are first initial and last name up to 8 letters. We also try to obfucator the email addresses on the web site, including the email address and the actual link. That cuts down on spam as well since they can't harvest the email addresses. We also do some in javascript.
