RE: [SAtalk] Postfix unknown user (peripherally related)

[Gary Smith]

Create a user called "blackhole" and then add the entry into the postfix configuration 
(/etc/postfix/virtual) that says (usually the last line)
 
@yourdomain.com        [EMAIL PROTECTED]
 
This basically says any lost mail goes to the blackhole user.  Then create a cron job 
similar to this:
 
:>/var/mail/blackhole
 
on a 1 hour interval or something like that.  Alternatively you can choose not to 
erase it and use it as a spam catch for feeding bayes.
 
It should work...

        Hey folks,
        
        Not 100% a spamassassin issue, but I've got a ton of spammers trying any
        address they possibly can on my domain. Postfix responds to each one
        with a 'reject: unknown user', but of course spammers don't use their
        own address and my mail queue gets insanely full (not quite to the point
        of a denial-of-service, but close). Does anyone know how to tell Postfix
        not to respond to emails sent to users that don't exist?
        
        Thanks,
        
        Greg
