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.
