Hi All:

What's the easiest way to block a maildomain from using our smtp  
server? We have some customers that have infected PC's that are  
sending out spam. We want to force them to use their ISP's outgoing  
mailserver but still allow them to connect to pickup mail from their  
inbox.


We have been blocking their IP's in /home/vpopmail/etc/tcp.smtp but  
since the IP's keep changing this is becoming tedious.


Require authorization for those accounts, and then deny SMTP auth for  
those users.


vmoduser -rs u...@domain
