Filter incoming messages for one particualr user

[Sean Brown]

Hello list.  Is this possible?:   Let's say I have a user "[EMAIL PROTECTED]", whose home directory is /home/mailuser.  I want to set things up so that mailuser only accepts messages from one particular e-mail address.  In other words, if the sender is any other address besides [EMAIL PROTECTED], mailuser will silently throw the message away.  If the message is from [EMAIL PROTECTED], it completes the instructions in mailuser's .qmail file (which right now forwards to three other addresses).   Is this possible?   Thanks,   Sean Get your FREE download of MSN Explorer at http://explorer.msn.com
